[Mesa-dev] [PATCH] swr: Add arch flags to support Cray and PGI compilers

[Chuck Atkins]

Note that the Cray flags (-target-cpu=) need to come first since the
cray programming environment uses wappers around other compilers.  By
checking the wrapper flags first, you can be sure to match the wrapper
flag instead of the underlying compiler (gcc, intel, pgi, etc.) flags.
