scripts: fix dumping config

libelf has been moved to being a companion library, now.

config: hide entries when in backend mode

This implies hidding entries for:
- binutils libraries
- dmalloc
- duma
- 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.

samples: fix samples

kernel/linux: add latest versions 2.6.32.10 and 2.6.33.1

debug/gdb: fix building the native tic

The native 'tic' will _always_ be run on the build
machine, so no need to handle canadian/native/...

libc/glibc: add patch to fix binutils version check

Older glibces were not ready to handle binutils >=2.20.
Fix that, and the forseeable future.

debug/ltrace: properly fix building for powerpc

ltrace uses ppc, whereas crosstool-NG use powerpc.
Fix that by passing the correct value to HOST when calling configure.

debug/ltrace: fix building on x86

ltrace uses i386 and x86_64, whereas crosstool-NG use x86 for both cases.
Fix that by detecting what bitness we're building for, and pass appropriate
i386 or x86_64 to ltrace's configure.

libc/uClibc: vampirise patches for 0.9.30.2 from builroot

Commit in upstream buildroot:
http://git.buildroot.org/buildroot/commit/?id=43ffd946ad569f3a1d0662de221cd4cb65bdc8e6
Everything on the 0_9_30 branch since the release (0.9.30.3 to be)

kernel/linux: add latest 2.6.32.9 and 2.6.33, remove old 2.6.32.x

complibs: remove headers after build

After the toolchain is built, we do no longer need the headers.
Reported-by: Enrico Weigelt <weigelt@metux.de>

binutils/binutils: add patch to default emulation for mips64

arch: add mips64

This adds initial mips64 config option and build script.

scripts: use more portable sed options

No need for extended regular expressions here.

scripts/samples: use the computed '$(sed)', not 'sed'

samples: fix this MIPS eglibc-based sample

Specify the SVN revision to use for the eglibc snapshot instead of HEAD,
as some patches made their way upstream in the meantime.

comp-libs: make libelf a companion library

When gcc-4.5 is out, it will require libelf. So better make it a
companion library now rather than postponing the ineluctable.

complibs: hide companion libraries for target entry

The companion libraries on the target are required only for internal use by
binutils and gdb. The user should not have to know about this, so hide the
option.

complibs: simplify config file

Although currently the wrapper is directly dependent on
companion libraries, let's still decorelate those two.

complibs: split-up selection for individual libs

binutils/binutils: fix using GMP and MPFR

scripts: fix dumping 'other environment'

Do not sort the environment, it cripples the output.

cc/gcc: simplify the _or_later stuff

scripts/showsamples: fix non-POSIX construct

scripts: add action to extract config from a build.log file

That got removed quite some time ago, but is really usefull to get the
configuration from a build.log file of a failing build.

kernel/linux: add latest 2.6.32.8

config: re-order the log entries inthe menuconfig

scripts: also dump the rest of the environment

scripts: use kernel name (uname -s) when system name (uname -o) is not availabe

'uname -o' is a GNU extension.

scripts/functions: fix date munging when ns are not available

On some systems (eg. *BSD and Darwin), date does not support nanoseconds
(%N) precision. Instead of printing '%N' in this case, it just prints 'N'.
Fix the sed expression to handle this case.

comp-libs/mpfr: fix build on Darwin

libc/eglibc: Add option to optimize for size

Add an option to eglibc to optimize for size using -Os.
