Adrien Béraud a20cb38659 arch: add support for "jaguar" AMD CPU optimisations 
AMD Jaguar ( https://en.wikipedia.org/wiki/Jaguar_%28microarchitecture%29 ) is
suddenly a popular architecture since it is used in the PS4 and the XBox One.
Many embedded systems are also likely to use it in the next years.

This patch adds support for GCC architecture-specific optimisations and
tuning for these CPUs.
These optimizations are available with GCC 4.8+.

Enter snapshot date to use for gcc.
Format is: A.B-YYYYMMDD
A is GCC major version, for example 4.
B is GCC minor version, for example 7.
YYYYMMDD is snapshot date, for example 20110430.
This way we'd get version 4.7-20110430

libmudflap is a gcc library used for the mudflap pointer
debugging functionality. It is only needed if you intend to
use the -fmudflap gcc flag.
See http://gcc.gnu.org/wiki/Mudflap_Pointer_Debugging and
the help of the gcc -fmudflap option for more details.
If you're unsure, leave this option disabled.
