Bump PORTREVISION for ports depending on the canonical version of GCC
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,
   c++11-lib, c++11-lang, c++14-lang, c++17-lang, or gcc-c++11-lib.

lang/clang3*, lang/clang-devel: set environment during build

The clang ports override the default build target, but the new targets
fail to set the environment like the default target does.  This patch
passes MAKE_ENV to environment.

It also combines compounds to a single make cmd and unsuppresses the
commands so the output shows on the build logs.
