MCONFIG: build GCCOPT one step at a time, don't align stack
Some gcc options are only valid together with other gcc options, so
build GCCOPT one bit at a time, and change gcc_ok to take already
existing GCCOPT flags into account.
This lets us build with -mpreferred-stack-boundary=2, which is only
valid on 32 bits and therefore with -m32.
