gcc: Add patch to resolve i*86 tune configuration overrides
When compiling gcc-runtime for i686 libatomic, libgomp and libitm are
compiled with additional '-march' and '-mtune' overrides. This typically
does not cause build errors (e.g. core2-32 tune), and results in less
optimally tuned outputs. However with specific TUNE_CCARGS (e.g. has
'-mfpmath=sse' but not '-msse*'), the build errors with conflicting
'-mfpmath' options.
This is caused by gcc-runtime specific configure scripts and Makefile
options that override by adding additional '-march'/'-mtune' args. OE
builds gcc-runtime differently to other build systems, and provides
target specific arch/tune options directly. As such, this change adds a
patch for gcc to remove the specific cases where the args are added.
