Long awaited, finally update the default version of GCC in the Ports

Collection as well as the lang/gcc port from GCC 4.8.5 to GCC 4.9.4!

See http://gcc.gnu.org/gcc-4.9/changes.html for an extensive list of
changes and http://gcc.gnu.org/gcc-4.9/porting_to.html for information
on how to port to that new version (if necessary).

files/java-patch-hier required adjustments, gcc/files/patch-arm-libcpp
is not needed any longer (merged upstream), and we're also loosing the
local Stack Protector patches/backports.

PR:		196712
Tested by:	antoine (-exp runs)
Supported by:	antoine, kwm, and others
