[LLVMdev] llvm build broken with "--enable-targets=x86, x86_64, arm"

[Jean-Daniel Dupas]

This is a known issue. 
To workaround it, you can remove either x86 or x86_64 in the configure line. 
FWIK, adding just one of this two target is enough to support both 32 bit and 64 bit architecture.

./configure --enable-optimized --disable-assertions --enable-targets=x86_64,arm --build=x86_64-apple-darwin10
