Subject: [PATCH] Initial testing support

Added the ability to compile a subset of functions in to a test
executable for Linux. To be used in the future for testing.

Removed unnecessary includes.

Tested working by compiling test executable for GNU/Linux and for the
3DS. The 3dsx was tested in citra.
