ltmain.in: Compiler dependencies wrongly deduplicated

Removing duplicate compiler dependencies causes linking problems on
linux with GCC libraries. This deduplication optimization is no longer
used for linux hosts.

Reported: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=75462

* build-aux/ltmain.in: Add linux to list of hosts that do not remove
  duplicate compiler dependencies.
* NEWS: Update.
