cc/gcc: cleanup the _or_later logic

So far, we've had a version always select appropriate _or_later option,
which in turn would select all previous _or_later options.

Because the dependencies on companion libs were cumulative, that was
working OK. But the upcoming 4.6 will no longer depend on libelf, so
we can't keep the cumulative scheme we've been using so far.

Have each release family select the corresponding dependencies, instead
of relying on selecting previous _or_later.

     8       Add support for the Signal Processing Engine.  This will set up
     9       the toolchain so that it supports the SPE ABI extensions. This
    10       mainly targets Freescale e500 processors.
    11       
    12       Setting this option will append "spe" to the end of your target
    13       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    14       configure/build system will know to include SPE ABI support.
    15       It will also automatically add "-mabi=spe -mspe" to your
    16       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
    17       so you do not need to explicitly add them.
