PATCH: Remove code duplication in dwarf2.c

Hi H.J.

Sort-of.  Andreas has just posted a patch to provide a global debug 
directory parameter to the call to bfd_follow_gnu_debuglink() which I 
would like to see integrated into your patch.  Plus it seems to me that 
there is a lot more code duplication between _bfd_dwarf2_find_line and 
_bfd_dwarf2_find_nearest_line, so maybe you could expand your patch even 
more ?

Cheers
