to build a baremetal only variant, no reason why this is not
allowed

cc/gcc: add 4.5.0

cc/gcc: add support for 4.5.0 or later versions

starting with 4.5.0, gcc requires libelf.

complibs/libelf: remove old versions

Those old versions are not suitable for use by gcc.

complibs/libelf: enable the host build

Host libelf is required by gcc-4.5.0

complibs/libelf: build target libelf in its own directory

debug/gdb: remove insight

Insight seems to be very slow to follow up on mainstreram gdb.
Latest snapshots are more than 6 months old.

Moreover, I don't have time to maintain insight support in crosstool-NG;
and, because I don't use it, I am unable to find any breakage.

debug/gdb: reorder options in the menuconfig

debug/gdb: allow static build with complibs

It is now possible to built static versions of the companion libraries,
so we can now build a static cross-gdb using the complibs.

scripts: don't print the build system guess warning

complibs/gmp: mark 5.0.1 as being experimental

MPFR can't cope with GMP > 4.x.y so hide it behind EXPERIMENTAL
until we fix MPFR

samples: add Blackfin sample

Add basic support for the Blackfin architecture

For uClibc, the name of the Blackfin architecture is 'bfin'. Actually,
the naming of the architecture is quite messy: for toolchain tuples
and uClibc, it's bfin, but for the kernel, it's blackfin. We've
arbitraly choosen to name it "blackfin" in Crosstool-NG.

Add Blackfin-related uClibc patch to fix a build failure related to
fork() being used in unistd/daemon.c.

Yann E. MORIN:
Apply the patch to the kernel/linux build script to use 'linux'
in the noMMU tuples. See:
http://sourceware.org/ml/crossgcc/2010-04/msg00010.html

scripts/functions: log the test strings

scripts/functions: compress with gzip level 3, as stated in the documentation

Thanks to Bruno Tarquini <btarquini@gmail.com> for the report.

scripts/functions: add a save/restore handler

Saving and restoring the steps requires saving/restoring multiple
directories. Depending on the configuration, some may not exist.

Add a wrapper that checks before creating/extracting the tarballs.

scripts/functions: fix CT_Patch again

Merge.

Revert 3ea4e6f7b85f: Force autoreconf for mpfr

upper-layer build system effectively forces the selection.

As discussed there: http://sourceware.org/bugzilla/show_bug.cgi?id=9678#c4

Reported by: Sasha Sirotkin <buildroot@browserseal.com>

config: fix style issues when source-ing files

Always enclose the sourced file between double-quotes (purely for
consistency; enclosing or not are both allowed by the kconfig language).

config: move backend-related options to their own file

config: hide arch and kernel selection when used as a backend

When used as a backend, it is the responsibility of the upper-layer build
system to set the target architecture and kernel.

config: hide options to debug crosstool-NG when a backend

When used as a backend, it does not make sense to debug crosstool-NG,
so hide the option.

config: hide more config options when a backend

Hide the prompts for some behavioral options, for which the upper-layer build
system is responsible for:
- parallel jobs and maximum load
- use pipes
- use custom shell

config: hide paths when used as a backend

When crosstool-NG is used as a backend, it is the responsibility of the
upper-layer build-system to properly set paths, so we just hide the
prompts in this case.

scripts/populate: optimise search loop

Curently, populate will iterate over all ELF (shared objects|executables)
to look for missing NEEDED DSOs, adding to the list at every iterations
of the search loop.

Instead of looking again at previously handled ELF files, recursively
resolve every ELf files.

Also, in case there are a whole lot of files (more than the shell can
accept as arguments list, or creating a command line longer than the
shell can cope with), use a temporary file with the list of files
to search for missing dependencies.

scripts/populate: cleanups and misc fixes

- it's a POSIX compliant shell script: drop bash, use /bin/sh
- fix help text
- use an absolute path for sysroot
- replace "echo" with "printf"
- replace "stat -c '%i'" with "ls -1id"
- replace "pushd / popd" with "cd / cd -"
- remove superfluous break
- bail out if required lib not found, except if forced

scripts/populate: fix handling the forced libraries list-file

If a list-file is used, then each library in the file will be handled
twice (not a real issue, as the second iteration will find the library
already present, just avoid doing the job twice).

scripts/populate: properly locate the sysroot and required tools

This fixes two problems:
- the sysroot might be in a sub-directory (think SYSROOT_DIR_PREFIX)
- it is not needed to have the target tuple to properly detect the sysroot
and the required tools

As a side effect, this script is now no longer dependent on the target
tuple, and in the future, we might be able to share it across many
toolchains (when/if we can install all of them in the same place).

scripts/populate: add -m option, to merge source and dest

Merge the source rootfs into the (pre-existing) destination rootfs,
and populate the result accordingly.

scripts/populate: add option to use an alternate sysroot

Add a new command line option, "-r", which allows the user to specify
an alternate sysroot location to copy libraries from. This is useful
when using the toolchain in combination with a separate root filesystem,
or when working with multiple different root filesystems.

binutils/sstrip: get rid of ELFkickers

ELFkickers are looong dead and unmaintained, and the sstrip
from buildroot is working fine *and* is maintained.

binutils/sstrip: depends on ELF

No point building sstrip is the target is not ELF.

tools: move sstrip to the binary utilities menu

sstrip is now alone in its 'tools' menu, and we will probably never gain
any other 'tool'. Besides, sstrip is just strip, but a little bit more
agressive, so it deserves going to the 'binary utilities' menu.

debug/gdb: gdb>=7.0 can use MPC, enable for cross-gdb

GMP and MPFR are optional for gdb, so offer a config option.

debug/gdb: can't build a static native gdb if using GMP/MPFR

so we can't build a static native gdb using them, obviously.

scripts: fix dumping config

config: hide entries when in backend mode

This implies hidding entries for:
- binutils libraries
- dmalloc

- native gdb
- ltrace
- strace
- sstrip

kconfig: silence a warning about undefined env variable

When using an environment variable to set a config entry,
don'twarn if it is not defined. Update doc accordingly.

config: prepare for build-system backend

When acting as a backend for a build-system, we should not build
any application that runs on the target, that is:
- no native gdb
- no companion libraries
- no binutils libraries
- no debug tools (save for gdbserver)
- ...

Here, we simply prepare the (hidden) config option that will detect
that we are acting as a back-end.

Update doc accordingly.
