Comment (by Phyx-):

 @Awson.

 I have `-Wa,-mbig-objs` setup in every call, and I'm using binutils 2.28
 which should have your patched included and I'm using a linker script to
 merge the sections back together. But I'm still getting an invalid exec
 format error from Windows when I try to run the exe.

 My assumption is that `-gc-sections` is removing a section it shouldn't
 be. Before I dive too much into this, did I miss a step? Since you seem to
 have a working version.
