You can use -i, --badreloc and --relocate (see rpm's man page). With
the proper use of these you'll get the other gcc rpm installed off
in some other directory like /opt/gcc-fc6. This may or may not work
well though depeding on how hard coded the search for various items
are within the gcc package. If it doesn't you'll need to just resort
to building and installing gcc yourself (which is not really that
hard).
If it does work you've got some new problems though. You can't
upgrade gcc now, as that will remove both gcc's. This will mean that
you can either:
upgrade one
reinstall the other.
install the new one
remove the old one
That last one is an "rpm -i" followed by an "rpm -e", and probably can
be reversed.
