* libcoff-in.h (xcoff_tdata): Change debug_indices to a signed long.
* libcoff.h: Regenerate.
* xcofflink.c (xcoff_keep_symbol_p): New function, using the
"skip" logic from xcoff_link_input_bfd.
(bfd_xcoff_size_dynamic_sections): Explicitly skip dynamic
objects in a dynamic link, rather than checking whether csectpp
is null. Always allocate debug_index for other objects,
and always go through the loop. Update the type of debug_index
after the change above. Read the auxillary csect information
and use xcoff_keep_symbol_p to decide whether a symbol should
be kept. Set its debug_index to -2 if not.
(xcoff_link_input_bfd): Update the type of debug_index after
the change above and always expect it to be nonnull. Use it to
test whether a symbol should be stripped, rather than making the
decision here. Postpone all symbol creation to the second pass.
