[BUILDROBOT, PATCH] config-list.mk: Extract target name correctly

[Jan-Benedict Glaw <jbglaw at lug-owl dot de>]

Hi!

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.

       * config-list.mk: Use shortest match for OPT to find the actual
       target name.
