Further cleanup, 11-RELEASE build fixes.

Prune unused dependencies via -Wl,--as-needed.

Build with as few requirements as works for 10.3-RELEASE and
11.0-RELEASE, i386 and amd64. This should use the base CC on anything
but 10.3-RELEASE amd64, where we use GCC 4.9 for OpenMP support.

Specifically, 11.0-RELEASE compilations do *not* work with GCC 4.9 and
the result fails with SIGBUS with apparent bogus SSE code generation and
misalignment.

Fix sound theme support via libcanberra (change Linux ifdefs to !Apple
ifdefs).

Apply -DPROC_TARGET_NUMBER="1" (i. e. build an executable with generic
tuning) only when building packages and unless -march is in CFLAGS.

USE_GNOME upgraded from gtkmm20 to gtkm24, and add devel/openmp as
requisite on amd64 (rather than implicit clang or gcc libs), bumping
PORTREVISION.

Silence cmake developer warnings, and be sure to export linker flags to
cmake (so it finds -lomp in its configuration phase)
[-DCMAKE_POLICY_DEFAULT_CMP0056:STRING=NEW]

Cleanups: leverage USES=localbase, and drop/avoid duplicate definitions
and dead code from the Makefile and support for unsupported older
FreeBSD releases.
