devel/freebsd-gcc9: Remove old GCC system toolchain

FreeBSD 13.0 and later can be compiled with devel/freebsd-gcc12
or devel/freebsd-gcc13 and GCC 9 is unsupported upstream.

devel/freebsd-gcc9: fix build with libc++ 17

When building relatively recent gcc ports (with C++ in them) against
libc++ 17, you get errors similar to:

*: Bump PORTREVISIONs for math/mpc update to 1.3.1

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.

compiler: use CHOSEN_COMPILER_TYPE instead of COMPILER_TYPE

CHOSEN_COMPILER_TYPE is the only safe variable to let a port know which
typer of compiler has been elected to be used by the framework

One more small cleanup, forgotten yesterday.
Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Update to MPC version 1.2.0 with the following changes:
 - New functions:
   . mpc_sum
   . mpc_dot
 - Several functions are more robust with a reduced exponent range
   (for example corresponding to IEEE 754 binary formats).
 - New mpcheck tool for comparison with the native C library (which
   is not installed by default).

Bump all directly dependent ports. Do not bump those indirectly
dependent via the lang/gcc* family since their run-time dependencies
and code generated should not be affected.

devel/freebsd-gcc9: fix build on powerpc64 elfv2

Use the same patch that was committed for lang/gcc9 to fix build.

PR:		243932
Approved by:	jhb (maintainer)

Add a new port for an external FreeBSD toolchain based on GCC 9.

This port provides external GCC toolchains for GCC 9.2.0 for the aarch64,
amd64, i386, mips, mips64, powerpc, powerpc64, riscv64, and sparc64
platforms.

Note that at present I am not yet able to build a full FreeBSD system
on any of these platforms, but it will be easier to debug the remaining
issues (which may be issues to fix in FreeBSD rather than the port) with
the packages available to other developers.
