OK, I will split up the patches into trivial fixes and document the changes to

Detecting cross compilers is not perfect right now, so I hooked up only the
native tests. If you know of a reliable way to detect the presence of cross
compilers, please let me know :)

Cross compilation tests are supposed to be called by providing a CROSS_CC env
variable populated with the installed cross compiler from the
build/<arch>-linux-user/tests/ directory (as documented in the arm Makefile

I did not touch the make files for most archs which already had the cross
compiler hard-coded. I can modify them to make them similar to what I did for
