AFAICT, GCC's EABI had been ignored by many people, because it was in 
poor shape for a long time and the only usable EABI compilers had been 
commercial.

IIRC, it was you, who had called arm-eabi gcc-4.6.x crap? Do you really 
expect it to be better in gcc-4.7.0?

If we adhere to GCC's decision, we need to remove the arm-rtems4.11 
toolchains and the arm target from RTEMS-4.11 right on the spot.
