Fix PR 425

[Alan Modra]

It's not clear to me why _bfd_link_section_stabs ignores nested B_BINCL
stabs in the code that optimizes header file stabs and thus decides that
the stabs for t1.o and t2.o are the same.  However, we run into the same
problem with R_*_NONE relocs if linking t1.o twice, ie. with
ld -r -o r1.o t1.o t1.o

	* syms.c (_bfd_stab_section_find_nearest_line): Ignore R_*_NONE relocs.
