drivers/firmware/efi/libstub/Makefile builds a static library, which
is not linked into the main vmlinux target in the ordinary way [arm64],
or at all [ARM, x86].
Since commit:
7f2084fa55e6 ("[kbuild] handle exports in lib-y objects reliably")
any Makefile using lib-y generates lib-ksyms.o which is linked into vmlinux.
In this case, the following garbage object is linked into vmlinux.
drivers/firmware/efi/libstub/lib-ksyms.o
We do not want to follow the default linking rules for static libraries
built under libstub/ so using subdir-y instead of obj-y is the correct
way to descend into this directory.
