c68360000c Fix loop optimization when ZOL is not available in xtensa configuration 
Currently building gcc for xtensa configuration with XCHAL_HAVE_LOOPS
set to 0 fails with the following error:

  xtensa.c:3952: undefined reference to `reorg_loops(bool, hw_doloop_hooks*)'

Only compile target-specific zero-overhead loop optimization code when
TARGET_LOOPS allows it.

2014-12-30  Max Filippov  <jcmvbkbc@gmail.com>

	* config/xtensa/xtensa.c (hwloop_optimize, hwloop_fail,
	hwloop_pattern_reg, xtensa_doloop_hooks, xtensa_reorg_loops):
	put under #if TARGET_LOOPS guard.

04a11c01de config-list.mk: Extract target name correctly 
With my last change, `sed' is used to cut out the target name from a listed
target. Since there may be additional OPTions encoded in the "target", I tried
to get only the first submatch before an `OPT'. However, `sed' uses longest
match, so I'm re-writing this using awk.

  If anybody is like using `gawk' or anything different, please feel free to
drop another patch. Since this is usually called by hand or by robots under
review, I don't see much of a problem here.
