Fix OptionalObsoleteFiles copy/paste mistake from r345236, which
connected libomp to the build. The comparison should not have been
against ${MK_OPENSSH}, but against ${MK_OPENMP}, obviously.
MFC r347979:
To avoid unnecessarily modifying ports, add a -lgomp symlink, since GCC
does not ship a -lomp symlink. Also update OptionalObsoleteFiles for
this, and add 32-bit variants while here.

MFC r345235:
Add lib/libomp, with a Makefile, and generated configuration headers.
Not connected to the main build yet, as there is still the issue of the
GNU omp.h header conflicting with the LLVM one. (That is, if MK_GCC is
enabled.)

MFC r345236:
Connect lib/libomp to the build.
* Set MK_OPENMP to yes by default only on amd64, for now.
* Bump __FreeBSD_version to signal this addition.
* Ensure gcc's conflicting omp.h is not installed if MK_OPENMP is yes.
* Update OptionalObsoleteFiles.inc to cope with the conflicting omp.h.
* Regenerate src.conf(5) with new WITH/WITHOUT fragments.

MFC r345242:
Explicitly link libomp.so against -lpthread, as it depends on pthread
functionality. This should make example OpenMP programs work out of the
box.

MFC r345278:
Also explicitly link libomp.so against -lm, as it transitively depends
on scalbn and a few other math functions, via libcompiler-rt. This
should allow OpenMP programs to link with BFD linkers too.

Remove --as-needed from the linker flags for libomp.so, as these
actually prevent the transitive dependency on libm.

Turn on MK_OPENMP for i386 by default, now that it can build.
