[gentoo-alt] Idea: external compilers in gcc-config

[Konstantin Tokarev]

Hi all,

I think it would be great to have a possibility to select "external" gcc profiles in gcc-config:
a) add "system" compiler if host system is shipped with decent gcc version;
b) add compiler from another Prefix installation.

This feature would significantly speed up bootstrap of Prefix eliminating at least one build of
gcc in Gentoo-friendly environments like Linux and Mac OS X, and give some additional
flexibility in building of system.
