White Screen (Big endian issues)

[Zombie-Ryushu]

With the latest Check out of tgbdual, I get a blank white screen launching any given rom. This has turned out to be a glibc error in the program on certain versions of glibc. The relevant warnings are here:

[cucholix]

have the same issue when loading content on Wii U

[andres-asm]

I just made it build, it was a long shot but I didn't really expect it to work.

[crystalct]

Surely TGB dual is not endian safe, so Big Endian machine like WiiU and PS3 are not supported.

@andres-asm out of curiosity how did you make this work?
