the problem occurs if there's a previous install dir of llvm(-gcc) in  
the PATH. there are similar problems when upgrading llvm, e.g.,  
tblgen appears to be taken from the previous installation instead of  
being rebuild. is this intentional or a bug?

however, even when building with a sane environment i get the  
following error both with and without --disable-multilib

can anybody give me a hint what might be going on?
