1.5: update version to 1.5.0

1.5: create maintenance branch for the 1.5 series

samples: update

libelf: add libelf-0.8.12

Merge.

configure: split has_or_abort in two: one to check, one to abort

Split the has_or_abort function in two:
- one that checks if the tool if found,
- one that calls the above check, and aborts if not found

The rational behind this is to be able to check for a tool
and if not found, fallback to using our bundled version,
should the need arise (and I get time).

Merge.

libc/glibc: don't use legacy snapshots

glibc snapshots have not been updated for about the
past 5 months. Consider them to be deprecated, now.

libc/glibc: remove dead code

The option to retrieve snapshots is already handled by
the generic 'specific date' and 'use latest' entries.
No need for a special case, as there's no code for it.

Merge.

debug/gdb: cleanup (remove) the static ncurses build

ncurses is built solely for the sake of building a native gdb.
The user should not rely on this library to build his/her userland,
but should rather build his/her own. So we remove it from the
sysroot after we successfully build the native gdb.

doc: update documentation, mostly eye-candy

sample: update the i686-nptl-linux-gnu sample

Update this sample, now it seems to correctly build again.

libc/eglibc: fix building for seemingly native toolchains

Build eglibc with -O2 as a fix/workaround to building
seemingly-native toolchains (see docs/overview.txt).

- docs/overview.txt
- docs/known-issues.txt

libc/glibc: fix building for seemingly native toolchains

Build glibc with -O2 as a fix/workaround to building
seemingly-native toolchains.

- docs/known-issues.txt
- http://sourceware.org/ml/crossgcc/2009-09/msg00055.html

samples: upgrade some samples

Upgrading all samples is too much a hassle.
Stick with those few for now.

samples: remove arm-beagle-linux-gnueabi

Use the generic arm-cortex_a8-linux-gnueabi sample instead.

Merge.

scripts: update config.guess and config.sub

readme: document patch description

gcc: ecjx.cc -> ecjx.o should use host compiler, not cross compiler

gcc: forward port gcc-4.4.0 patchset to 4.4.1

kernel/linux: update versions.

Insert an empty line bwetween added new versions.

debug/ltrace: fix build with /exotic/ linux-host OS

For ARM EABI hosts (ct-ng's target), the tupple ends in 'gnueabi'
For uClibc-based toolchains, the tuple ends in '-uclibc.*'
Make ltrace recognise those tuples as being the same as 'linux-gnu'

Merge.

samples: correclty fix saving samples with a C library config file

samples: fix uClibc config file location

comp-libs/cloog: fix building

For CLooG/PPL 0.15.3, the directory name was simply cloog-ppl.
For any later versions, the driectory name does have the version, such as
cloog-ppl-0.15.4.

config: fix indentation for options marked EXPERIMENTAL or OBSOLETE

Change the 2-space separation into a 1-space separation, for the sake
of homogeneity.

scripts: add new version at top of choice

Add new versions at the top of the choice menu, not at the bottom.

config: re-order menu entries so that latest versions are at the top

It makes better sense to have latest versions at the top of the choice
entries.

Merge.

samples: update

comp-libs/mpc: add latest 0.7 version.

comp-libs/cloog: new versions have the version number in the dir name

For CLooG/PPL 0.15.3, the directory name was simply cloog-ppl.
For any later versions, the driectory name does have the version, such as
cloog-ppl-0.15.4.

samples: fix saving samples

Use a correct sed pattern when setting CT_PREFIX_DIR

libc/eglibc: fix download

Fix the test to check if download is forced.

Merge.

kernel/linux: add latest versions

Add 2.6.27.33 as long-term stable, and 2.6.30.6 and 2.6.31.

gcc: add patch to fix EABI for armv4t

As pointed out by Martin GUY, gcc incorrectly generates armv5t
instrcutions for EABI, even for cores that are an armv4t.
The new patch (for the 4.3 series) fixes the problem by downgrading
the default CPU for EABI to being an armv4t core.

kconfig: allow stdin/stdout redirection

Allow stdin/stdout redirection for the CLI conf (not mconf).
This allows to recall a sample and automatically apply the defaults
to new configuration option, with something like the following:
yes "" |ct-ng "sample_name"

docs: add a tutorial on how to build a toolchain on Mac OS-X

Add a step-bystep tutorial to build a cross-toolchain on Mac OS-X.

companion libs: add latest CLooG/PPL versions

Add the latest 0.15.{4,5,6,7} CLoog/PPL.

samples: show the PPL, GLoog/ppl and MPC versions

When displaying a sample, do show the PPL, CLoog/ppl and MPC versions

samples: fix displaying selected tools

Do display selected tools / debug facilities when displaying a sample.

samples: replace usage of echo with printf

Using printf instead of echo allows easier and better formatting.

tools wrapper: fix building

Remove the build tools only after the wrapper is built.
Use the corect C compiler to build the tools wrapper.
Use the correct log level.

crosstool.sh.in: better mesage when creating script-overrides

log functions: fix CT_DoLog and CT_DoExecLog

$@ and $* are different when in double quotes; use $* to print the message.

tools wrapper: move choice selection to a more appropriate place

Move the tools wrapper choice selection down to the companion libraries
sub-menu, to avoid the user going back and forth in the menu.

tools wrapper: fix config dependency

The tools wrapper is not needed only for canadian crosses, but also
for every other type of toolchain.

docs: typo in overview.txt

TODO: update

Add TODO list for m4, autoconf, automake and libtool.
Building our own versions would remove burden from the users
who have older versions on their distributions, and are not
ready/able/allowed to upgrade.

config.{gues,sub}: update

config: move the patch choice to the extract section

Choosing the origin of the patches to apply is best
done in the 'extract' section.

config: add fallback to patch order

Add the possibility to fallback to either bundled or local patches
if local or bundled are missing.

config: add the local,bundled patch order

This ordering first applies the local patches, then the bundeld ones.

config: make selecting the patch origin a choice rather than a bool

functions: do not over-detect error when patching
