crosstool-ng: config/arch/powerpc.in@3ba2a43353df

Rationalise ./configure
- borrow a lot of ideas from Michael ABBOTT ( http://sourceware.org/ml/crossgcc/2008-12/msg00030.html )
- should be conforming to POSIX 1003.1-2008, non compliance due to bashsims is to be considered a bug
- as a result, it now works with dash
- make a little easier to read in some places
- enforce 4-space indentation
- get rid of futile 'return $?'
- quote all variables assignments
- save and restore IFS prior to and after using alternate values
- simplify the TOOLS_TO_CHECK listing

What's left:
- provide a mean to actually _compare_ version numbers
- change the TOOLS_TO_CHECK pattern style to be able to use '|' in regexp

     8       The PowerPC architecture, as defined by:

     9         http://www.ibm.com/developerworks/eserver/articles/archguide.html

    11 config ARCH_POWERPC_SPE

    12     bool

    13     prompt "Enable SPE support"

    14     default n

    15     help

    16       Add support for the Signal Processing Engine.  This will set up

    17       the toolchain so that it supports the SPE ABI extensions. This

    18       mainly targets Freescale e500 processors.

    20       Setting this option will append "spe" to the end of your target

    21       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc

    22       configure/build system will know to include SPE ABI support.

    23       It will also automatically add "-mabi=spe -mspe" to your

    24       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,

    25       so you do not need to explicitly add them.
