Alexey Neyman 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.

Crosstool-NG Build Status

Crosstool-NG follows the autoconf dance. So, to get you kick-started, just run:

./configure --help

If you are using a development snapshot, you'll have to create the configure script, first. Just run:

./bootstrap

You will find the documentation in the directory docs. Here is a quick overview of what you'll find there:
