Hi,
And another RTEMS-patch, I'd like to apply to GCC trunk and
GCC-4_7-branch: Adding microblaze*-rtems* target.
This patch has been in use as part of the RTEMS gcc-4.7 patches for ca.
1/2 a year.

* config.gcc (microblaze*-*-rtems*): New target.
* config/microblaze/rtems.h: New.
* config/microblaze/t-rtems: New.
