Totally. You essentially only need the /usr/lib/gcc-lib. /usr/bin/gcc
itself is pretty much a "wrapper", but copying it along and renaming
it can be helpful to avoid the somewhat cumbersome command line
options to switch backends. Also note that a matching binutils set
would be helpful.

The build is looking for specific versions? Why not just go into the
build scripts and have it skip that bit?
