Add support for AMD Agesa wrapper code. Patch 5 of 8.
This code fixes a number of build issues related to the AMD Agesa code.
The particular issues are global variables existing in romstage and the
use of GCC intrinsics in the build. The former issue will be addressed
shortly, and the latter issue requires community assistance. This code
is dependent on the AMD Family 14h mainboard code.
