No problem, I was just making a suggestion to improve test coverage. :)

If you compile with hardfp and run on Ubuntu, the binary will probably not
run at all due to ABI differences.  I'm not an ARM expert though, so take
whatever I say with a grain of salt.

I've tried using LLVM natively on a PandaBoard with ArchLinuxARM, but I
could never get Clang to finish building because ld kept running out of
memory. :)  It hasn't been important enough for me yet to set up a
cross-compiler.
