d8988dbe0b cc/gcc: modify to build gcc-4.8-based cross-tools
Building cross-tool based on gcc-4.8 fails while "Installing
pass-2 core C compiler", because building libgcc.mvars needs
libbacktrace.a that gcc.sh doesn't build. This patch inserts
a few lines configuring, and making libbacktrace into gcc.sh
to build gcc-4.8-based cross-tools successfully.

e284b218a7 arch/avr32: Fix download of header files
This patch fixes the download of the avr32 headers in crosstool-ng by
fetching them directly from Atmel's web site instead of the now-broken URL
given by the original author of the avr32-header-fetching modification,
who fetched them from a copy on his own, now-defunct server.

It also adds the necessary logic to extract from a zip file, as that is
how the headers are packaged.

To configure it for avr32 after launching ct-ng menuconfig in an empty
directory:

       Paths and misc options ->
               Shell to use as CONFIG_SHELL = sh
       Target options ->
               Target Architecture = avr32
       Toolchain options ->
               Tuple's alias = avr32
       Binary utilities ->
               binutils version = 2.18a
       C compiler
               gcc version = 4.2.2
       C-library
               newlib version = 1.17.0
               Enable IOs on long long = yes
               Enable IOs on floats and doubles = yes
               Disable the syscalls supplied with newlib = yes

CONFIG_SHELL is necessary to get round the "fragment: command not
found" bug when binutils-2.18 is configured using bash.

Prepared against crosstool-ng mercurial trunk on 31 March 2012.

150f500426 arch: allow adding a suffix to the arch-part of a tuple
For some architectures, it is legit to have an alternate value in the
'architecture' part of the tuple. For example:
    armv5te-*
    armv7a8-*

Besides, some packages expect the tuple to reflect the arch variant
(eg. openMPI) to detect the variant's capabilities (eg. atomic
primitives).

This patch adds an option for the user to specify a suffix to be added
to the arch-part of the tuple.

c1d673203d arch/arm: add option to use *eabihf tuples
Toolchains that use the hard-float ABI now are to be denoted by a tuple
ending in *eabihf, while the prevbious *eabi is now an indication that
the toolchain uses the softfloat ABI.

This is purely a cosmetic thing, for distros to differentiate their
hardfloat-ABI ports from their softfloat-ABI ports.

(note: softfloat ABI does not mean that it is using softfloats; it can
be using hardfloat instructions, but using the softfloat ABI).

  - pass those extra flags to components

e1806b1d22 kernel/linux: fix using custom location
Currently, extract and patch are skipped as thus:
  - using a custom directory of pre-installed headers
  - a correctly named directory already exists

Otherwise, extract and patch are done.

The current second condition is wrong, because it allows the following
sequence to happen:
  - a non-custom kernel is used
  - a previous build only partially extracted the non-custom sources
  - that p[revious build broke during extraction (eg. incomplete tarball...)
  - a subsequent build will find a properly named directory, and will
    thus skip extract and patch, which is wrong

Fix that by following the conditions in this table:

Type                  | Extract | Patch
----------------------+---------+-------
Pre-installed headers |    N    |   N
custom directory      |    N    |   N
custom tarball        |    Y    |   N
mainstream tarball    |    Y    |   Y

components also.

071606c0a0 scripts/gcc: Canadian Cross skip -print-multi-lib log output
Attempting to ${CT_TARGET}-gcc -print-multi-lib will fail

In do_cc_core_backend, for the final compiler in a canadian cross
baremetal, warn that multi-libs cannot be determined

In do_cc_backend, for either final compiler for a canadian cross,
warn that multi-libs cannot be determined

(Plus fixed CT_PREFIX_DIR in do_cc_backend to be ${prefix})
