[Bug ld/3290] Linker creates dynamic debug symbols in DSO

[jakub at redhat dot com]

--- Additional Comments From jakub at redhat dot com  2008-03-25 15:06

Do we need to do this even when info->relocatable?  PGI apparently uses
(or used?) global symbols in .debug_info sections and referenced them from
within object's .debug_info section.  With this change, ld -r
on one or more *.o files which define such global symbols will make those
symbols STB_LOCAL and so a final link fails.  IMHO either the debug symbols
should be made global, but hidden, or made local only when not ld -r.

works for me.
