Commit b7f05445c0 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)
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.
This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.
There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.
The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

During an exp-run for llvm 13 (see bug 258209), it turned out that
lang/erlang and lang/erlang-runtime2[13] fail to build with clang 13.
What appears to happen is that for these versions of erlang, PGO is
enabled, and it first builds a PGO-enabled beam.smp:
gmake[5]: Entering directory '/wrkdirs/usr/ports/lang/erlang/work/otp-OTP-21.3.8.24/erts/emulator'
if utils/gen_git_version amd64-portbld-freebsd14.0/gen_git_version.mk; then touch beam/erl_bif_info.c; fi
echo " PROFILE beam.prof.smp"
PROFILE beam.prof.smp
rm -f obj/amd64-portbld-freebsd14.0/opt/smp/erl*.profraw
set -e; LLVM_PROFILE_FILE="obj/amd64-portbld-freebsd14.0/opt/smp/erlc-%m.profraw" \
ERL_FLAGS="-emu_type prof +S 1" erlc -W -DPGO \
-o obj/amd64-portbld-freebsd14.0/opt/smp test/estone_SUITE.erl > obj/amd64-portbld-freebsd14.0/opt/smp/PROFILE_LOG
after which it does a test run, and uses llvm-profdata to merge the
profiling data into beam_emu_pu.o:
llvm-profdata merge -output obj/amd64-portbld-freebsd14.0/opt/smp/default.profdata obj/amd64-portbld-freebsd14.0/opt/smp/*.profraw

Later, it runs dtrace over all the collected objects, and this dies:
dtrace -G -C -Ibeam \
-s beam/erlang_dtrace.d \
-o obj/amd64-portbld-freebsd14.0/opt/smp/erlang_pu_dtrace.o
... long list of objects ...
dtrace: failed to link script beam/erlang_dtrace.d: an error was encountered while processing obj/amd64-portbld-freebsd14.0/opt/smp/beam_emu_pu.o
gmake[5]: *** [amd64-portbld-freebsd14.0/Makefile:1005: obj/amd64-portbld-freebsd14.0/opt/smp/erlang_pu_dtrace.o] Error 1
gmake[5]: Leaving directory '/wrkdirs/usr/ports/lang/erlang/work/otp-OTP-21.3.8.24/erts/emulator'
Something in beam_emu_pu.o (emitted by clang or llvm 13) is tripping up
dtrace, but I have very little knowledge about dtrace so I need help
here. :)
Now some other erlang runtimes such as lang/erlang-runtime24 *do* build
successfully with clang 13, but this is only because upstream disabled
the PGO feature, as a side effect of
https://github.com/erlang/otp/commit/b165524c732 ("erts: Implement the
BeamAsm JIT"):

I am unsure why upstream disabled this "for now", as it has been
disabled for more than a year. So, for now, work around the dtrace
failures by disabling PGO using the configure flag --disable-pgo, when
building with clang >= 13.
