gcc: Remove patch causing ICE on x86_64 valgrind compile
| ../../valgrind-3.12.0/VEX/priv/host_ppc_isel.c: In function 'iselInt64Expr':
| ../../valgrind-3.12.0/VEX/priv/host_ppc_isel.c:3270:1: internal compiler error: Segmentation fault

| Please submit a full bug report,
| with preprocessed source if appropriate.
| See <http://gcc.gnu.org/bugs.html> for instructions.
| rm -f libvexmultiarch-amd64-linux.a
| Makefile:1813: recipe for target 'priv/libvex_amd64_linux_a-host_ppc_isel.o' failed
Remove the patch to gcc causing this until the issue can be figured out.
