Remove old crt1.S. Moved crt0.S to crt1.S.
Changed to produce crt1.o instead of crt0.o to look more like glibc.
or1k: add or1k_dev_defconfig

This config turns on many more features and enables debugging.

This configuration isn't really meant to be run on a real system,

to use in a real system.  It's really meant for developers and for
testing in the simulator.
or1k: add or1k to the default ARCH choices based on uname
