File Makefile:

PS11, Line 154: 	util/xcompile/xcompile $(XGCCPATH) > $(xcompile) || rm -f $(xcompile)))
Should we redirect stderr to /dev/null just in case? The `include` below
should give a reasonable error message if something goes wrong but any
output of the `$(shell )` call would likely result in a mess.
