misc/seabios: Update to 1.16.0; use binutils binaries

Upstream release information:
https://www.seabios.org/Releases#SeaBIOS_1.15.0
https://www.seabios.org/Releases#SeaBIOS_1.16.0

When ports set USE_BINUTILS=yes, the environment is adjusted with, e.g.,
OBJDUMP=${LOCALBASE}/bin/objdump, so that binaries from devel/binutils
are used during the build.  SeaBIOS, however, ignores these environment
variables, so supply them to MAKE_ARGS.  This will fix the build when
/usr/bin/llvm-objdump is linked to /usr/bin/objdump.  See PR 267854.

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.

misc/seabios: Add NO_ARCH

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

Remove # $FreeBSD$ from Makefiles.

Convert misc/seabios to use the new "build" argument to USE_GCC,
replacing direct manipulation of RUN_DEPENDS by the much more
declarative and simpler USE_GCC=yes: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.

in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.

This includes ports
 - featuring USE_GCC=yes or USE_GCC=any,
 - featuring USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and those
 - with USES=compiler specifying one of openmp, nestedfct, c11, c++0x,

seabios: fix failure to find python

The failure has been reported by the automatic builders:

http://package19.nyi.freebsd.org/data/103i386-default-build-as-user/412304/logs/errors/seabios-1.9.1.log

This is because SeaBIOS doesn't have a configure phase and the paths of the
required build tools need to be passed to the make command when building.
