make: avoid problems with mv aliases

Make fails to update .xcompile in case there is an mv alias preventing
silent overwrites of existing files. To avoid ambiguity, invoke mv
from standard location.

While we are at it, drop the code creating a unique .xcompile instance
before copying it into destination: this was done for the case of
running multiple independent make processes in parallel, but there is
a problem with this approach with multiple processes copying their
unique copies into the same destination file.

The tool running multiple make invocations in parallel should
explicitly invoke xcompile first.
