Followup security/nss installation path modification in r525484

PR:		243835

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.

Fix build on mips* and powerpc64

PR:		231715
Submitted by:	Piotr Kubaj <pkubaj@anongoth.pl>
Sponsored by:	IntegriCloud

Mark ports broken on mips64 that are already broken on powerpc64.  In
most cases, the failure mode is the same.  Also, mark them broken on
mips when necessary.

While here, pet portlint.

Approved by:	portmgr (tier-2 blanket)

Mark ports broken on powerpc64, categories o-z.

While here, pet portlint and do some other cleanup.

New port: security/py-python-nss

python-nss is a Python binding for NSS (Network Security Services)
and NSPR (Netscape Portable Runtime). NSS provides cryptography
services supporting SSL, TLS, PKI, PKIX, X509, PKCS*, etc. NSS is
an alternative to OpenSSL and used extensively by major software
projects. NSS is FIPS-140 certified.

NSS is built upon NSPR because NSPR provides an abstraction of
common operating system services, particularly in the areas of
networking and process management. Python also provides an abstraction
of common operating system services but because NSS and NSPR are
tightly bound, python-nss exposes elements of NSPR.
