If we can do that it would be nice.

We already try to do that -- Makefile looks for
config-host.mak in the source tree and suggests a
rune involving distclean. The check isn't perfect,
though (and nor is the Linux kernel's -- I lost an
hour or so the other week to a problem that turned
out to be stale junk in the kernel source tree that I
fixed with a 'make mrproper').
