*: 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.

math/R: Update to version 4.0.0

Also bump PORTREVISION of ports that depend on math/R.

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.

- Update to 0.21.0
- Fix LICENSE section

Bump PORTREVISIONs of all users of math/mpc that we just updated to
version 1.1.0 (via revision 464079).

qa: add check for NO_ARCH

If NO_ARCH is set then check that no FreeBSD elf(5) files are in $STAGEDIR.
If an elf(5) file is bundles as part of the package, but is not meant to be
run directly (i.e. the elf(5) file is a payload, and not compiled) then
those files can be added to NO_ARCH_IGNORE to avoid the check from failing,

Changes to ports:
 - Ports that have NO_ARCH set, but actually compile files have had NO_ARCH
   removed.
 - Ports that have elf(5) payloads have had those files added to
   NO_ARCH_IGNORE.
 - R-cran ports that do not set USES=cran:compiles have NO_ARCH set,

- Add new port: math/R-cran-NMF

  Provides a framework to perform Non-negative Matrix Factorization
  (NMF). The package implements a set of already published algorithms
  and seeding methods, and provides a framework to test, develop and
  plug new/custom algorithms. Most of the built-in algorithms have
  been optimized in C++, and the main interface function provides an
  easy way of performing parallel computations on multicore machines.
