textrels are bad for forcing copy-on-write (this affects everyone),
and for security/runtime code generation, this affects security ppl.
But in either case, it doesn't matter who needs textrels, it's
the very fact that they're needed at all.

2006-06-10  Ned Ludd  <solar@gentoo.org>, Mike Frysinger <vapier@gentoo.org>

	* bfd/elflink.c (bfd_elf_final_link): Check all objects for TEXTRELs.
	* ld/ldmain.c (main): Change textrel warning default to true.
	* ld/testsuite/lib/ld-lib.exp (default_ld_simple_link): Scrub TEXTREL
	warnings from ld output.
