What if the count was 11? or 21? I'm just mentioning we need to improve
that command!

I'm slightly surprised there aren't more hardlinks for gcc in here. A
meta-toolchain-sdk tarball will probably have a load of hardlinks in too
if you want something to test with (we don't usually make extX images
for the toolchain though).

Cheers,
