Subject: [PATCH] Do not use libtool -export-symbols option

This option is intended for libtool, not for any linker.
Check the support of --version-script option using an empty
list of symbols to catch some faulty linker supporting that
option but not allowing not existing symbols (some buggy mold
versions).
