Martin Storsjö accb06120c configure: Use dllexport/dllimport for data symbols across DLLs with mingw 
This avoids having to use pseudo relocations.

The version script used for exporting functions is skipped as soon
as the set of object files contains symbols marked with dllexport,
therefore we need to use makedef to produce the full list of symbols
to be exported.
