microblaze: Fix crt bootstrap
Rework crt bootstrap to work with the new __uClibc_main(),
and hardwire crt init/fini code since the awk approach to generating it on
the fly doesn't work for microblaze. The output from the gcc 4.1.2 compiler
is scrambled so that the tags expected by the awk script to bracket the
init/fini entry and exit code no longer do.
