Bump PORTREVISIONS for ports depending on the canonical version of GCC and
lang/gcc which have moved from GCC 4.8.5 to GCC 4.9.4 (at least under some
circumstances such as versions of FreeBSD or platforms), part II.

The first part covered ports with USE_GCC=yes, USE_GCC=any, or one of
gcc-c++11-lib, openmp, nestedfct, c++11-lib as well as c++14-lang,
c++11-lang, c++0x, c11 requested via USES=compiler.

This adds ports with USES=fortran and ports using Mk/bsd.octave.mk
which in turn has USES=fortran.
