FYI:

I've extended my branch for testing tune files:
http://git.openembedded.org/openembedded-core-contrib/log/?h=jansa/tune2-test
to test not only DEFAULTTUNE with fake MACHINES but all combinations of
MACHINES and DEFAULTTUNEs.

Script is still running but I've already found some old issues like
1) missing thumb in armv5te-vfp (and higher)
2) little endian PACKAGE_ARCHs included in big endian tunes

And while I was there I've added some possibly usefull tunes like
cortexa8t-neon and armv6 without vfp (we had patch for this for almost a
year).

I'll send pull request for this branch
http://git.openembedded.org/openembedded-core-contrib/log/?h=jansa/tune-fix
after finishing testing.

I also plan to compare AVAILTUNEs on cortexa9 device with "openssl speed",
like hrw did:
