{RC_CFLAGS="-arch x86_64 -arch i386"}

No idea at all why those braces are getting in there, but fixed in r62543.

I don't believe r62543 actually fixed it, because I still see the problem when trying to build mesa for i386 on Snow Leopard. I undid r62543 and fixed it differently in r63184. I believe this does actually fix it.
