But wait...  Here's what I've come up with:

+$(patsubst %,install-%,$(boottargets-y)) install-vmlinux: vmlinux
+	$(Q)$(MAKE) $(build)=$(boot) BOOTIMAGE=$(boot)/$(subst install-,,$@) install

I think this will work.  It would at least make PPC_MULTIPLATFORM usable:

$ make INSTALL_MOD_PATH=/target/g5 INSTALL_PATH=/target/g5/boot install-zImage.vmode
$ make INSTALL_MOD_PATH=/target/pseries INSTALL_PATH=/target/pseries/boot install-zImage

I'll do some more testing and post the resulting patch.
