[PATCH 0/1] MR3173: winegcc: Disable exporting all symbols on mingw targets.

[Jacek Caban (＠jacek)]

Mingw targets export all symbols by default if there is no explicit export. We generate export table in winebuild and don't use explicit exports. This may make linker generate an unused export-all table.
