[PATCH] linker regression fix

["Jan Beulich" <JBeulich at novell dot com>]

The patch in http://sourceware.org/ml/binutils/2005-04/msg00325.html
causes
local absolute symbols, including .file ones, to be removed from the
linker
output. This patch tries to adjust this.

Built and tested on i686-pc-linux-gnu, x86_64-unknown-linux-gnu,
ia64-unknown-linux-gnu, and for a large number of cross targets.

	* elflink.c (elf_link_input_bfd): Check for absolute symbols
before
	deciding to remove those not in any output section.
