Hi Bowen,

> CC=clang \

Is it possible that this is a clang compilation bug ?

I tried to reproduce the problem using a toolchain built with gcc
rather than clang, and nothing went wrong.

Looking at the code it is hard to see where the uninitialised value
might occur.  The fnmatch function is being called with two pointers,
match->triplet, which has already been tested in the for() loop header
and which has static initialisation anyway, and name, which should 
have been set in set_default_bfd_target().

Cheers
  Nick
