cc/gcc: pass the companion libs prefix to cc_core

In case of canadian-cross, the companion libraries are not the same for
the core cc (they run on 'build') as they are for the final cc (they run
on 'host').

Prepare for this differentiation (coming later), while retaining the
current behavior (to use the same compblibs).

    13 Hrm. gcc puts .arch ev4 into the .s, and this overrides -mev6 for as.
    14 I cannot really think of anything better than
