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.

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/arachne-pnr: fix build with GCC-based architectures

Building with GCC9 fails with:
src/util.hh: In instantiation of 'std::set<typename M::key_type> keys(const M&)
[with M = std::map<CBit, bool>; typename M::key_type = CBit]':
src/chipdb.cc:73:23:   required from here
src/util.hh:191:24: error: moving a local object in a return statement prevents
copy elision [-Werror=pessimizing-move]
  191 |   return std::move(keys);
      |                        ^
src/util.hh:191:24: note: remove 'std::move' call

As reported at https://github.com/YosysHQ/arachne-pnr/issues/134

Add -Wno-error=pessimizing-move to CFLAGS for GCC build.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

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, everything INDEX-11 shows with a dependency on lang/gcc9 now.
