Update the default version of GCC used in the Ports Collection from

GCC 4.6.4 to GCC 4.7.3.  This entails updating the lang/gcc port as
well as changing the default in Mk/bsd.default-versions.mk.

This adds powerpc64 as a supported architecture (and removes ia64,
though it can be supported by manually installing lang/gcc48).

New binaries %%GNU_HOST%%-gcc-ar47, %%GNU_HOST%%-gcc-nm47, and
%%GNU_HOST%%-gcc-ranlib47 are provided to support link-time
optimization (LTO) which scales significantly better.

And it adds support for indirect functions (IFUNCS), experimental
support for transactional memory in the compiler as well as a supporting
run-time library called libitm, a new string length optimization pass,
and support for atomic operations specifying the C++11/C11 memory model.

Version 3.1 of the OpenMP specification is now supported for the C,
C++, and Fortran compilers.

GCC accepts the options -std=c11 and -std=gnu11 for the C11 revision
of the ISO C standard which inlcude support for unicode strings,
nonreturning functions (_Noreturn and <stdnoreturn.h>), alignment
support (_Alignas, _Alignof, max_align_t, <stdalign.h>), and a
__builtin_complex built-in function.

The C++ frontend now accepts the -std=c++11, -std=gnu++11, and
-Wc++11-compat options and implements many C++11 features of the
language including extended friends syntax, explicit override
control, non-static data member initializers, user-defined literals,
alias declarations, delegating constructors, atomic classes, and more.

The C++ standard library and Fortran frontend have received many
improvements.  See http://gcc.gnu.org/gcc-4.7/changes.html for an
extense list of changes; http://gcc.gnu.org/gcc-4.7/porting_to.html
for information on how to port to that new version.
