All build sets for RTEMS 4.11 that where using GCC 4.7.2 have been
updated to GCC 4.7.3. This release uses a new patch from the
rtems-tools git repo.
The AVR tools have the target CFLAGS forced to '-O2 -g' to work
around bugs in the AVR GCC compiler related to the default
optimizations used when building the various run-time libraries.
