lang/perl5*: Link with -pthread instead of -lpthread

During configure of security/p5-Crypt-GCrypt a test program is
compiled and run to test libgcrypt.  This program segfaults when perl5
is built with the THREADS option.  Libgcrypt links with libgpg-error
which has an init function which calls into libintl (gettext) which
calls pthread functions before libthr is initialised.

The compiler command line is provided by perl and it includes both
-pthread and -lpthread.  Patch perl to remove -lpthread.  With -pthread
the compiler will pass -lpthread to the linker such that it is
initialised early.

Discovered by the exp-run for gettext 0.22.

While here also remove -lc unconditionally and remove the code that
replaced it with -lc_r for old version of FreeBSD because the version
test is incorrect (missing a dot).  The -pthread flag already tells
the compiler to use -lc_r on those old versions.

lang/perl5*: remove workarounds for lld 15 and dtrace enabled

After https://cgit.freebsd.org/src/commit/?id=be39466a1035, there is no
need anymore to patch the perl5 Makefiles to add
"-Wl,--allow-multiple-definition" to the linker flags. They should now
link with lld 15 and later without any issues.

lang/perl5*: alternative workaround for lld 15 and dtrace enabled

Modify the workaround committed in 4ae8ff941b29 by only adding
-Wl,--allow-multiple-definition to the two link command lines that
require it, instead of adding it to hints/freebsd.sh

Otherwise, that linker flag is emitted into perl's global configuration
(/usr/local/lib/perl5/5.xx/mach/Config_heavy.pl), and might be used by
other ports which link in libperl, such as www/mod_perl2, which cannot
correctly handle any unexpected linker flags, leading to errors.

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.
