For *FLAGS it would be ideal if we didn't need them at all.  If
"gcc49 -o test test.c" would just work I think they can be removed from
bsd.gcc.mk.  In fortran.mk they probably need to stay because some ports
link gfortran object files using "${CC}" or "${CXX}" which may be clang.

There's another problem though, with the *_DEPENDS lines.  They depend
on lang/gcc unconditionally while GCC_DEFAULT is supposed to be a user
tunable.  The dependency should be on lang/gcc${_GCC_VER}, but then
${_GCC_VER} and ${GCC_DEFAULT} would have to be empty to depend on
lang/gcc which is awkward.  Would it be possible to get rid of lang/gcc
by moving it to lang/gcc47?  That would make the gcc ports similar to
the other ports that use the default-versions system like lang/perlXYZ
or www/apacheXY etc.
