Since commit 799c43415442 ("kbuild: thin archives make default for
all archs"), core-y is passed to the linker with --whole-archive.
Hence, the whole of stub library is linked to vmlinux.
Use libs-y so that lib.a is passed after --no-whole-archive for
conditional linking.
The unused drivers/firmware/efi/libstub/relocate.o will be dropped
for ARCH=arm64.

This patch touches under arch/arm64/, but
this is more related to efi.
I am sending this to Ard.

Ok, I'll ignore this then. Ard -- please yell if you want me to do anything
else with it.

I am going to send a batch of EFI fixes early next week, so I can take
this as well, or alternatively, you can apply it directly.

No, please take it. Just wanted to make sure it didn't slip through the
cracks, that's all.
