The script figures the archs according to the 'meta/conf/machine/include',
this is incorrect since it only searches the oe-core layer, I will fix it.

And where can I get the "om_gta01 om_gta02 om_gta04 ..." archs? I mean which
layer are they in? So that I can test them.

This seems terrible, I don't know what's wrong currently, I will try to fix it 
tomorrow.
