Gustavo Zacarias f39ceddcf7 package/gcc: cleanup arch/cpu combinations 
Cleanup arch/cpu combination limits, we had super-wide depends and it
doesn't help readability, version bumps or testing.

Make the bool/depends/select order the same for all entries.

Drop redundant limitations, for example sparc* if sparc wasn't
supported in general.

Power8 requires at least gcc 4.9.

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.

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.
