Makefile: Write .xcompile to $(obj)

This file was being written to the root src directory. It is the only
file being written to src while all others are being written to obj. I
decided to leave .xcompile in the cleanup targets so any stale compies
will get removed on clean.

This is part of my incremental rebuild work. It saves a few targets from
being rebuilt.
