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

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

[Matthew Gretton-Dann]

[-- Attachment #1: Type: text/plain, Size: 2503 bytes --]

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

looks fine, except one missing chunk from my original patch. maybe left out
intentionally.

This change isn't in your commit to trunk of 2012-10-15 which is what
I backported.  This is because Richard Earnshaw effectively made this
change when he removed FPA support (SVN rev 188510).

I'm happy to do a patch that makes this change - but I think it should
be a separate patch to this backport one.

Thanks,

Matt

I'll defer to the arm maintainers for this.
