[LLVMdev] llvm-gcc bootstrap failure

[David Greene]

I'm getting the following when building llvm-gcc with an optimized set of
LLVM libraries:

I don't understand the reference to stmp-multilib since I configured with 
--disable-multilib.

Is anyone else seeing this?  This is affecting my ability to test patches I 
want to commit.
