Thanks Uwe! That was kind! I'm on Fedora but I guess I can find the
multiarch binutils :) I'll try that tomorrow when I'm back at the
office. Let's see what kind of results I can get from it.

Unfortunately bunch of the GPIOs depend on x86 - so I need to see what
I can compile in with decent effort. For my compile test I just hacked
the Makefile to force all in and added some dummy macros to fix few
missing functions :| But I guess I can get some results.
