Ticket #2409: fix of GModule detection and usage.
Don't mix GLib and GModule compiler and linker options. Use gmodule-no-export if present to avoid use -Wl,--export-dynamic option with some linkers. If gmodule-no-export is not available, use generic gmodule. Signed-off-by: Andrew Borodin <aborodin@vmail.ru>
