The --vmm configure option was added to distinguish between the two virtual
machine managers that kvm-unit-tests supports, qemu or kvmtool. There are
plans to make kvm-unit-tests work as an EFI app, which will require changes
to the way tests are compiled. Instead of adding a new configure option
specifically for EFI and have it coexist with --vmm, or overloading the
semantics of the existing --vmm option, let's replace --vmm with the more
generic name --target.

Changes in v2:
* Removed the RFC tag and cover letter.
* Removed --vmm entirely.

We should only emit this TARGET=qemu to the config.mak when we're
arm/arm64, since that's what the help text says. Also, because the help
text says that the --target option is only for arm/arm64, then configure
should error out if it's used with another architecture. The nice thing
about this rename is that we can get that right this time. We didn't error
out with --vmm, but we should have. Erroring out on an unsupported
feature allows us to add support for it later without the users having
to guess if it'll work or not.
Thanks,
drew

You're right, I'll fix it for v3.
