configure: check for lzma

Some packages are available as LZMA tarballs. LZMA is a relatively recent
compression algorithm; it's slightly better than bzip2, but offers much
faster decompression. LZMA is now deprecated in favor of XZ, but some
packages switched to LZMA when XZ was not yet available, or still in its
infancy. Latest XZ (which totaly obsoletes LZMA) offers a backward LZMA-
compatible utility, so we can check for 'lzma' nonetheless.

      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.
