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.

    15         There are two versions of linuxthreads.  The older (stable) version

    23       From the uClibc config option help:

    24         The new version has not been tested much, and lacks ports for arches

    25         which glibc does not support (like bfin/frv/etc...), but is based on

    26         the latest code from glibc, so it may be the only choice for the

    27         newer ports (like alpha/amd64/64bit arches and hppa).

    46       Say y if you want uClibc to support localisation.

    56       If you see issues with using pre-generated locales data,

    57       you can try switching this off.

    58 

    59       If so, please report the issue, so we can default this

    60       to off if too many people complain.
