Since 11017f081f, the Crosstool-ng
backend generates toolchains that have a prefix inconsistent with what
Buildroot expects. Buildroot expects a "buildroot" vendor name, while
Crosstool-NG builds toolchain with the "unknown" vendor name.
This is causing build failure such as:
http://autobuild.buildroot.org/results/15b2c0e50a81b86dd13af684c9254df2bc0df8de/build-end.log
Fix this by changing the vendor part of the tuple used by Crosstool-NG
to "buildroot".

since its initial introduction. It requires some special handling that

Practically speaking, MIPS has three useful ABIs:
* o32 is for 32-bits CPUs, or 64-bit CPUs running only a 32-bit subset
of the instruction set.
* n32 is for 64-bits CPUs only. It has 32-bits pointers and long
integers.
* n64 is for 64-bits CPUs only. It has 64-bits pointers and long
integers.
See http://www.linux-mips.org/wiki/MIPS_ABI_History and
http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64 for more
details.
So, this commit reworks the Buildroot MIPS support by:
* Add separate mips64/mips64el top-level architectures.
* Renaming the n32 ABI option to BR2_MIPS_NABI32, for consistency
with BR2_MIPS_OABI32.
* Renaming the n64 ABI option to BR2_MIPS_NABI64, for consistency
with BR2_MIPS_OABI32.
* Make the n32 and n64 ABI selections select the BR2_ARCH_IS_64,
since those ABIs are valid on 64-bits CPUs only.
* Removing the o64 ABI, which is practicaly never used.
* Removing the "none" ABI, which really doesn't make sense.
* Introduce the mips64 and mips64el architecture names when a 64-bits
MIPS ABI is choosen. This will fix build issue like
http://autobuild.buildroot.org/results/9b8c5ea86c953a89e85e7b67e9221de41773f652/build-end.log
where gmp was confused by the fact of having a 32 bits architecture
(detected by the mips- architecture part of the tuple) but 64 bits
integer size when compiling.
* Adjust the uclibc.mk logic to support the new mips64/mips64el
architecture names, and take into account the renaming of the ABI
options.
This has been build tested by generating Buildroot toolchains and
compiling a few packages for MIPS o32, MIPS n32 and MIPS n64.
This work is originally based on prior work done by Gustavo Zacarias.

Commit ba92d6ef68 made hard float the
default when Cortex-A8 and Cortex-A9. The problem it was trying to fix
is that the newer Linaro toolchains (2012.05 and 2012.06) are
hard-float, so the default selection of soft-float enabled on ARM
doesn't work for those toolchains.
Unfortunately, not selecting soft-float causes problems with
the Crosstool-NG backend at the moment.
As an intermediate solution, make the soft float option disappear when
using external toolchain: the toolchain will decide by itself whether
to generate hard float or soft float code.

duplicated (because all modern x86 CPUs can be both used as i386 or

x86 CPUs that do not support the 64 bits instruction set are hidden.

Cortex-A8 and Cortex-A9 ARM cores are guaranteed to provide a hardware
floating point unit, so there's no reason to default to software
floating point for them.
More importantly, the newest Linaro toolchains are hard float
toolchains, so basically an user choosing those toolchains and leaving
the default option of software float would run in compilation issues.
So let's make hard float the default for Cortex-A8 and Cortex-A9.

The check_glibc function verifies that the C library of the external
toolchain is glibc. To do so, it verified that a file matching
ld-linux*.so.* or ld.so.* was found in the lib/ directory of the
toolchain's sysroot. However, with the Linaro 2012.05 toolchain, the
lib/ directory contains two links named ld-linux-armhf.so.3 and
ld-linux.so.3, which means that the first ld-linux*.so.* wildcard
expression expands to two files, which generates a syntax error for
the "test" program. We replace that with a more elaborate find+wc
combination to determine whether at least one matching file is
present.
The check_arm_abi function verifies the ABI of an ARM toolchain. For
EABI, it tested that the target name ends with eabi. However, with
Linaro 2012.05, the tuple is now arm-linux-gnueabihf (for hard float),
so we have to adjust the logic to accept this additional "hf"
specification in the tuple.

With the modified configuration, the user is presented with the
following options:
- Toolchain type: Buildroot toolchain | External toolchain | Ct-ng toolchain
In case of External toolchain:
- Toolchain: the CodeSourcery toolchains | Custom toolchain
- Toolchain origin: Toolchain to be downloaded and installed | Pre-installed toolchain
In case of Toolchain to be downloaded, the user is presented with:
- Toolchain URL
In case of Pre-installed toolchain, the users sees:
- Toolchain Path
For CodeSourcery toolchains, the toolchain URL field is not used (the
URLs are directly coded in ext-tool.mk).

Decimal floats were introduced circa gcc-4.2 or -4.3, and requires
the floating-point environement fenv.h in the C library.
The uClibc .config file used by crosstool-NG to build uClibc is the
same as used by the internal buildroot mechanism, and explcitly
disables fenv support.
The quick workaround is to simply disable decimal floats in all
crosstool-NG config files.
In the long run, it might be better to check this situation, and/or
add code and/or options in crosstool-NG to handle this (but it is
much more involved, and this workaround is sane).

In order to use locale support on a Linux system, you need locale data
to be present:
* on a (e)glibc based system, this data is typically in the
/usr/lib/locale/locale-archive file, which can be created and
extended using the localedef program
* on an uClibc based system, the set of supported locales is defined
at build time by an uClibc configuration option.
This patch implements generating locale data for the following cases:
* Internal toolchain
* External toolchain based on (e)glibc. uClibc external toolchains
are not supported, because with uClibc, the set of supported
locales is defined at build time. CodeSourcery and Linaro
toolchains have been tested, Crosstool-NG toolchains are believed
to work properly as well.
* Toolchains built using the Crosstool-NG backend, but only (e)glibc
toolchains.
This feature was runtime tested with internal uClibc toolchain,
CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a
simple C program that shows the data and a gettext translated message.
Note that this option differs from the "purge locales" option, which
is responsible for removing translation files and other locale stuff
installed by packages. At some point in the future, we may want to
clarify the respective roles of those options.

When the crosstool-ng backend is used, host-gawk is built as a
dependency of the crosstool-ng package, and therefore an host 'gawk'
binary is installed in $(HOST_DIR).
When the target gdb package is also selected, this unfortunately leads
to a build failure, as reported on
http://buildroot.humanoidz.org/results/f19c0499d08212d8b5100fa9434e1197092957db/build-end.log.
The problem is that the ./configure of gdb detects gawk in the PATH,
but at compile time, it fails to find gawk. This is due to the fact
that the gdb compilation process is started without the correct path.
This patch fixes this by passing $(TARGET_MAKE_ENV) in the environment
of the gdb compilation process.
A better fix would be to switch gdb to the AUTOTARGETS infrastructure
in the future.

Starting from 2012.03, the Linaro toolchains have separated the GCC
support libraries (libstdc++, libgcc_s) from the sysroot itself. So we
no longer have the case where all libraries are inside the sysroot, as
we had for all the previously supported toolchains.
Therefore, we add some logic to detect if such a separate directory is
used for GCC support libraries, and if it's the case, we make sure
that we take into account this directory when creating our own
sysroot, and when copying libraries to the target filesystem.
