scripts/functions: test for decompressors before use

./configure does check for the presence of gz and bzip2, so we can
safely use them in the build scripts.

On the other hand, more recent formats (eg. XZ) are not yet widely
available, and we do not want, and can't, force the user to install
them as a pre-requisite.

So, build up a list of allowed tarball formats based on the available
decompressors. For no, this is a static list, but the upcoming XZ
support will conditionnaly add to this list.

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

     8
      the toolchain so that it supports the SPE ABI extensions. This

      mainly targets Freescale e500 processors.

      Setting this option will append "spe" to the end of your target
yann@1634
    12
      tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
yann@2467
    13
      configure/build system will know to include SPE ABI support. It
yann@2467
    14
      will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
yann@2467
    15
      and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
yann@2467
    16
      do not need to explicitly add them.
