I do not believe there is. Since `make ...' starts the Kbuild system,
Kbuild would have to support this otherwise we would have to
circumvent the build system. And the closest thing to some kind of
support I could find was in scripts/Makefile.host, but it says it is
for binaries used during the kernel compilation process. I think this
set of userspace utilities is further complicated by its use of
autotools.

My use of "circumvent the build system" may be a bit harsh. I don't
think there is anything wrong with running a parameterized instance of
make within a target, but the short answer would be that this problem
does not seem to have been generalized in Kbuild yet.
