[RFA/4.7/ARM] Backport arm-*-linux-gnueabihf triplet support to 4.7

[Matthew Gretton-Dann <matthew dot gretton-dann at linaro dot org>]

All,

This patch backports Matthais Klose's arm*-*-linux-gnueabihf triplet
support patch of 2012-10-15 to 4.7.

The backport was not clean as 4.8 has obsoleted various arm*-*-*
triplets which are valid in 4.7.

I have tested this cross with arm-none-linux-gnueabihf and
arm-none-linux-gnueabi.

One question I do have having done this work - is there a canonical way to 
test for the arm*-*-linux-gnueabi triplet (or variants)?  Various configure 
and testsuite files test for this, but there doesn't seem to be a consistent 
method.

OK for 4.7?

Thanks,

Matt
