winegcc library creation/import broken.

[Peter Dons Tychsen]

Hello again,

It smells a bit like, but this time for libraries and not executables:

https://bugs.winehq.org/show_bug.cgi?id=50731
https://bugs.winehq.org/show_bug.cgi?id=50755

But that is first broken in 6.3 and i am running 6.2.

And again, it only breaks for winelib created libs and not executables.

Thanks,

/pedro
