As like as HEAD(14.0-RELEASE) llvm16 was merged in base for 13.2-STABLE
with the OSVERSION 1302507.

- Utilize USE_CXXSTD=c++14 or similar solution where applicable
- Update conditionals to addtionally check for OSVERSION greater than
  1302507 and less than 1400000

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

games/libretro-bluemsx: fix build on powerpc64le

Src/SoundChips/OpenMsxYM2413.cpp:331:10: error: constant expression evaluates to
-3 which cannot be narrowed to type 'char' [-Wc++11-narrowing]
        7, 3, 0,-3,-7,-3, 0, 3,

Since it should also fix build on other architectures with unsigned char,
unbreak on aarch64 and riscv64 (untested).

For ports on riscv64 that fail the same (or similar ways) to aarch64, mark
them BROKEN.

While here, pet portlint (Makevar order).

games/libretro-*: Update libretro cores and fix path

Update cores and fix path.
Some users complain than cores are installed in libexec instead of lib where
RetroArch looks. So emulators will work out of box.
