Well, for one, it is still marked experimental in crosstool-NG, so it is
not the default.

Second, this tuple is now correctly recognised by config.{guess,sub}:
    http://git.savannah.gnu.org/gitweb/?p=config.git;a=commitdiff;h=0783756885327f171aab844db8ad331b8586ed62;hp=626f5d2f5ee2e5effe8a4671cc9b223c2dc1148d

Third, the issues were essentially lying in gcc, which did not treat
*-*gnueabihf as an EABI tuple, and thus the gcc build would break. Since
a few weeks now, gcc properly handles *-*gnueabihf as an EABI tuple:
    http://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config.gcc;h=9255d118c5094879715cc26410106028536b2273;hb=931645bc159f79ff57d4d6a64bbe6682be24e7c0#l868

Since gcc now no-longer recognises OABI, it is always EABI, so the file
above will correctly treat arm*-*gnueabihf as an EABI tuple.

So, all in all, the packages that will cause issues are those that
hand-parse the tuple (such as openMPI:
    https://github.com/open-mpi/ompi-svn-mirror/blob/master/config/opal_config_asm.m4#L810
which is broken anyway, since not all tuples have the ARM variant in them).

So, I don't expect too much breakage in the short-term. Besides, this
tuple is already used by Ubuntu (and Debian, being the origin of this
new terminology).
