413f5f6100 Super-H multilib toolchain fixes
1. On SuperH, configuring GCC with explicit variant of the CPU
(like "sh4") limits the default set of multilibs to just that CPU
and requires --with-multilib-list to change. Allow for "unspecified"
variant, so that we can defer to GCC to determine the list.

2. Support toolchains with both endiannesses at the same time.

3. Add a SuperH/newlib sample

4. Add more flags processing for uClibc

3ebc5d0c1e libc/*.sh: Deprecate libc_check_config step.
This step was only used in uClibc. However, with upcoming multilib, the
config management will have to be done for each variant differently,
anyway.

uClibc was the only user of libc_check_config step, as well as
CT_CONFIG_DIR directory. Retire these.

Two other clean-ups in uClibc.sh:
- KERNEL_HEADERS check seems to be bogus, this config option is not
  present even in 0.9.30 - which is not supported already.
- SHARED_LIB_LOADER_PREFIX was renamed to MULTILIB_DIR in 0.9.31,
  according to ChangeLog - and MULTILIB_DIR is passed from command line
  instead.

34ecc718d9 arch/all: Add common function to return multilib target
This code was abstracted out of Cody P Schafer's multilib patch.
It doesn't seem right having architecture dependent code in a
specific libc implementation script. So this patch breaks it out into
scripts/build/arch/<arch>.sh in a function:

  multilib_target_to_build="$(CT_DoArchMultilibTarget 'multi_flags'
'target-in')"

Note that this function gets called on each multilib variant with
different sets of compiler flags supplied in 'multi_flags'. The caller
will first filter the flags so that there is no conflicting flags (e.g.,
no '-m32 -m64') supplied.

Changed by Alexey Neyman:
- make option analysis check specific option rather than match global
  options string as a whole. Moreover, old code did not handle multiple
  options in the same multilib, e.g. '-m64 -mlittle'.
- fixed substitutions in powerpc.sh (*le variants did not match the
  pattern in the shell parameter expansion)
- make s390.sh actually apply the flags it gathered from the options.
- straighten the spaghetti in x86.sh by setting two flags, arch & abi.
  Also, do not depend on "gnu" being the last part - we can have
  '*-uclibcx32', for example.

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.

395dca5ea8 arch/microblaze: add new architecture
Add Microblaze architecture support.

This depends on EXPERIMENTAL, as upstream projects do not yet
include full support to build a modern microblaze compiler.
This is in the process of being updated, but is not currently
publicly accessible.
