If you have a VERSION file (not VERSION.cache), the build won't look
for VERSION.cache, nor try to build it.  It's not the ideal solution,
nor is aliasing hg to "echo" with some arbitrary string as argument.
I tend to build Go on the host computer, specially after a recent "hg
sync" (or "hg pull"), then reanme VERSIOn.cache to CACHE.  If you
delete VERSION* before the build:

	$ cd $GOROOT/src
	$ rm -f $GOROOT/VERSION
	$ ./all.bash &&
		mv $GOROOT/VERSION.cache $GOROOT/VERSION

then subsequent Plan 9 builds will work.

Also, while you're at it, add an arbitrary "echo" at the end of
make.rc and remove the leading dot in ".  ./make.rc" in all.rc to
allow the procedure to run without interruption.  The tests are still
incomplete, though, in my experience.

PS: This works for me for 386 and arm.  Let me know if you encounter
any further problems, by now I ought to know all possible tricks :-)
