Normalize names of some source files
Most tdep/nat files are named:
<cpu>-<os>-tdep.c
<cpu>-<os>-nat.c
A few files do not respect this scheme. This patch renames them so that
they are consistent with the rest of the files. It builds fine with
--enable-targets=all, but that doesn't test the nat files. I can only
hope that my grep skill is good enough.
