Yes, Make will notice if it has a dependency rule for a file
included via 'include foo' (or for the makefile itself). In
this case we 'include config-host.mak', and config-host.mak
has a rule which says it depends on configure (and on pc-bios ???)
which triggers a rerun of configure.

I also notice that we have a "TODO: this code can be removed
after QEMU 1.7" in the run-configure rune :-)
