One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories a

Add USES=xorg, USES=gl and in a few cases USES=gnome to ports in categories
starting with 'a'.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Prepare for powerpc-on-clang by deleting hard-coded tests for libstdc++.so
as a stand-in for "are we running on gcc".

For people already testing powerpc on clang, it is possible that they
already have both compilers in base.  Thus, the assumption that "gcc is
in base" (e.g.  libstdc++.so exists) always means "force use of GCC" is
already broken.  It will be for everyone on -CURRENT once the switch is
made.

While here, standardize on compiler:c++11-lang instead of -lib (they are
equivalent these days), pet portlint, and do some other cleanup.

audio/nekobi-lv2: fix build with GCC-based architectures

This port requires C++11-compatible compiler to build on GCC architectures.

Additionally, remove -mtune=generic -msse -msse2 on GCC architectures.
