Remove LLVM 5.0 as it has no remaining dependencies and has expired.

PR:		236412

Deprecate and slap an expiriation date on llvm50.

Don't override the compiler on armv7.

The base system compiler is now sufficent to build and link.

No version bump.  While technically required for armv7, forcing everyone
to rebuild for this minor change that doesn't effect actual use is not
justifiable.

Do not set OPTIONS_SUB twice

Change cmake default behaviour to outsource.

Ports that build out of source now simply can use "USES=cmake"
instead of "USES=cmake:outsource". Ports that fail to build
out of source now need to specify "USES=cmake:insource".

I tried to only set insource where explictely needed.

Bump PORTREVISION for ports depending on the canonical version of GCC
defined via Mk/bsd.default-versions.mk which has moved from GCC 7.4 t
GCC 8.2 under most circumstances.

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, as a double check, everything INDEX-11 showed depending on lang/gcc7.

Use exec in wrapper to avoid an extra shell process sticking around.

I purposely didn't bump PORTREVISION for this as it's not really
worth a rebuild even though technically required.

Limit LLVM builds to linking a single binary at a time.

Regular builds can requires multiple gigabytes of memory at Debug builds
can exceed 100GB.  This should help low-memory systems such as
Raspberry-Pis and VMs.

Bump PORTREVISION for ports depending on the canonical version of GCC
in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.

This includes ports
 - featuring USE_GCC=yes or USE_GCC=any,
 - featuring USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and those
 - with USES=compiler specifying one of openmp, nestedfct, c11, c++0x,
   c++11-lib, c++11-lang, c++14-lang, c++17-lang, or gcc-c++11-lib.

devel/llvm*: Fix wrapper scripts to support symlinking to them

The wrapper scripts currently do not resolve the real path to $0:

Here /usr/local/llvm50/bin/clang should be called not

lld: accept EINVAL to indicate posix_fallocate is unsupported

As of r325320 posix_fallocate on a ZFS filesystem returns EINVAL to
indicate that the operation is not supported. (I think this is a strange
choice of errno on the part of POSIX.)
