This patch does not look right: It replaces an option sequence

  --as-needed -lgcc_s --no-as-needed -lgcc -lc --as-needed -lgcc_s 
--no-as-needed -lgcc

that has balanced uses of --as-needed/--no-as-needed with an option sequence

  --as-needed -lgcc_s

that leaves --as-needed in effect for the later linker options.

Oh yeah. This particular bug was unknown to me. But 'ksh' has a long-
standing reputation of being buggy. (Maybe because it was long used
by proprietary systems, which did not have bug trackers like modern
distros have?)
