COFF fix
There is an egregious bug in COFF handling code resulting in that any object
file containing more than 32768 sections is broken.
The problem is that 'n_scnum' is declared 'short' in include/coff/internal.h.
This leads to that PE+ bigobj format implementation doesn't in fact work
properly and also explains why having 2**16 sections as specified by Microsoft
never worked before (only 2**15 worked).
This also doesn't match other BFD code, where 'target_index' is declared 'int'
in 'bfd_section' structure.
I've attached the patch solving the problem.
