Looks like --disable-tools results in qemu-ga being
the only entry in $TOOLS.

With the filter added in my patch, this results in install-prog
getting called with an empty list, which generates the error.

So now we need an extra check to avoid calling install-prog with an
empty list. I'll post a patch today. Thanks for the catch.
