Fix diagnostic on "gnu.warning" section

[Vladimir Prus <vladimir at codesourcery dot com>]

At the moment, if ld sees a symbol in "gnu.warning", it will emit a warning of 
the form:

	<some.file>: warning: warning: <warning text>

with the word "warning" repeated twice. This patch fixes this and adds a test 
for the right message. OK?

	* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
	Don't prepend "warning" to the message.
