[PATCH] winegcc: Align sections in PE files to page size.

[Rémi Bernon]

This makes sure it will be possible to mmap the section directly instead
of having to copy them. It then also makes perf able to figure the code
origin for Wine modules.

I'm resending just this one as I am now trying to upstream PE support
directly in Linux perf. This should still be useful to avoid copying
sections when Wine modules are loaded.
