[patch] Fix false warning: section .dynbss not found in ...

[Jan Kratochvil <jan dot kratochvil at redhat dot com>]

Hi,

this is a follow-up on:
	http://sourceware.org/ml/gdb-patches/2010-02/msg00345.html
	http://sourceware.org/ml/gdb-patches/2010-02/msg00345.html

found two new sections by prelink:
	Reading symbols from /usr/bin/gdb...Reading symbols from /usr/lib/debug/usr/bin/gdb.debug...
	warning: section .dynbss not found in /usr/lib/debug/usr/bin/gdb.debug

Checked the prelink source (again) and I see no more of them there now.

No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.


Thanks,
Jan

	* symfile.c (addr_info_make_relative): Ignore also missing ".dynbss"
	and ".sdynbss".  Simplify the comment.
