Use Debug FNA3D for PowerPC

[Fancy2209]

For some reason I haven't figured out, MojoShader can only realize when a Effect file is valid on Big Endian if FNA3D is built as Debug.

Should we comment the release build temporarily? We can probably strip -S the debug build for uploading as well.

(On the topic, I wonder which -O level it breaks down on?)

Oh yes, commenting it out is a better approach

Also strip was borked iirc, I believe it's a bug in binutils as I haven't been able to strip binaries using cross binutils for PowerPC or PowerPC64, only on actual hardware

Ok that's fixed, I should've realized the fix was using powerpc-unknown-linux-gnu-strip.
I've made icculus/mojoshader#80 for debugging the issue on Release further.
By the way if you'd like I can help setting up a VM to test PPC and PPC64 on.
