[RFA:] Prepend "warning: " to "user" linker warnings, as ELF does.

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

The ELF section warning construct was recentlish (2003-08-04)
changed to have "warning: " prepended, so for symmetry I suggest
all (i.e. including the a.out stabs construct) do the same (or
I'll have to submit the corresponding a/symmetric patch to
newlib).  I expect even less breakage on a.out, compared to the
ELF-only change. ;-)  No test-cases need be adjusted, but
forthcoming test-cases depend on this.

Since the ELF warnings go through here, that "warning: " string
would be doubled, so I removed it.  Yay, removed code!
Translating "warning: " for *those* messages in ldmain.c is now
inconsistent; other "warning: " strings aren't.  Should they all
be translated or left alone?

Ok to commit?

bfd:
	* elflink.c (elf_link_add_object_symbols): Don't add "warning: "
	prefix here.

ld:
	* ldmain.c (warning_callback, warning_find_reloc): Prepend
	"warning: " to warning messages.
