ltmain.in: Fix reordering --as-needed

Libtool was reordering flags like, --as-needed, which broke its usage,
since the relevant libraries were no longer following the flag.

Reported: https://savannah.gnu.org/support/?111213

* build-aux/ltmain.in: Add check for --as-needed and --no-as-needed
  flags.
