[ARM] Add arm-linux-gnueabihf triplet support.

Hi,

The patch adds arm-linux-gnueabihf triplet support.

No regression for arm-linux-gnueabi tests.

There are some differences between testsuite results on softfp Natty
builders and the new hard float Precise builders. But none are due to
the change in triplet.

Thanks!
