  Add a new knob WITH_DEBUG_FILES to control the building of standalone
  debug files for userland programs and libraries.  The "-g" debug flag
  is automatically applied when WITH_DEBUG_FILES is set.

  The debug files are named ${prog}.debug and ${shlib}.debug for                  consistency with other systems and documentation.  In addition they are
  installed under /usr/lib/debug, to simplify the process of installing
  them if needed after a crash.  Users of bsd.{prog,lib}.mk outside of the
  base system place the standalone debug files in a .debug subdirectory.
  GDB automatically searches both of these directories for standalone
  debug files.

GCC: bring back experimental support for amdfam10/barcelona CPUs.

This is a revised subset of the support initially brought in in r236962
and later reverted. The collateral efects seem to have disappeared but
it is still recommended to set the CPUTYPE with caution.

While here also install AMD intrinsics header ammintrin.h

When gcc 4.2.0 was imported, the 3DNow intrinsics header  was
not added to the list of intrinsics headers to install, so belatedly (5
years :) add it.

When the needed configuration update to libstdc++ was done.
we overlooked  that expl hasn't been merged. This is causing
breakage in  some ports.
