   This patch corrects a bug in sh_elf_reloc_loop.  A value is saved by
   a function for the next time it is called, but the variable used for saving
   it isn't static.

My general philosophy when maintaining BFD was to make all the
functions reentrant.  Therefore, no variables should be static.  I
would have stored the data in the BFD somewhere.
