Using core-y is not the correct way to get kbuild to descend into
arch/x86/boot/startup. For instance, building an individual object does
not work as expected when the pattern rule is local to the Makefile
$ make arch/x86/boot/startup/map_kernel.pi.o
GEN Makefile
CALL /home/ardb/linux/scripts/checksyscalls.sh
DESCEND objtool
INSTALL libsubcmd_headers
make[3]: *** No rule to make target 'arch/x86/boot/startup/map_kernel.pi.o'. Stop.
make[2]: *** [/home/ardb/linux/scripts/Makefile.build:461: arch/x86] Error 2
make[1]: *** [/home/ardb/linux/Makefile:2011: .] Error 2
make: *** [/home/ardb/linux/Makefile:248: __sub-make] Error 2
So use obj-y from arch.x86/Kbuild instead, which makes things work as
expected.
