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.

devel/libunwind: Cosmetic change

- Use bsd.port.options.mk + bsd.port.mk instead of bsd.port.pre.mk +
bsd.port.post.mk
- Use = for PLIST_FILES

devel/libunwind: use base system unwind.h

- Add --disable-cxx-exceptions so libunwind does not implement the
  _Unwind_* API and does not use its internal unwind.h.  The base
  system libgcc_s provides this API.  This was already the upstream
  default for most architectures.
- Add --disable-unwind-header to prevent installation of unwind.h.
  Instead, install an unwind.h that forwards to the base system
  unwind.h, but not on FreeBSD 14 where all implementations of
  unwind.h (base, lang/gcc*, and devel/llvm*) are compatible.

devel/libunwind: set LLD_UNSAFE

libunwind.so has symbols with ELF protected visibility which various
test applications could preempt. Both GNU gold and LLVM's lld fail to
link this case, with errors like

lld:
/usr/bin/ld: error: cannot preempt symbol: _ULx86_64_init_local
>>> defined in ../src/.libs/libunwind.so
>>> referenced by Lperf-trace.c
>>>               Lperf-trace.o:(main)

gold:
/usr/local/bin/ld.gold: error: Gperf-simple.o: cannot make copy relocation
    for protected symbol '_Ux86_64_local_addr_space', defined in
    ../src/.libs/libunwind-x86_64.so

For now prevent libunwind from linking with lld. More information can be
found in libunwind upstream issue 58
