portability: work around a "busybox sed" limitation
* configure.ac: While every other sed tested supports usage like
'/\(re\)/{s//\1/;...<NEWLINE>}', and POSIX appears to requires this,
busybox's sed does not support it. So duplicate the regexp:
'/\(re\)/{s/\(re\)/\1/;...<NEWLINE>}'. Reported by Vincent Lefevre:
<http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/13013>.
