cross-compilation doesn't solve all issues, in all cases; while you
can build stuff, you cannot really test it - and stuff like support
for GL/GLES extensions can only be discovered and tested at run time.

the Mozilla build farm has a bunch of Tegra-based boxes used to build
and test the ARM targets, for instance.
