[COMMITTED] ld: cris*-elf: Default to --no-warn-rwx-segment

[Hans-Peter Nilsson]

Thankfully, all framework bits were already in place for
controlling the default setting for --[no-]warn-rwx-segment
per-target.
------------ 8< ------------

ld:
	configure.tgt (cris-*-*, crisv32-*-* sans *-aout and *-linux): Unless
	specified through the --enable-* -option, default to
	--no-warn-rwx-segment.
