    arm64: Adjust EFI libstub object include logic · ad08fd49

    Commit f4f75ad5 ("efi: efistub: Convert into static library")
    introduced a static library for EFI stub, libstub.
    The EFI libstub directory is referenced by the kernel build system via
    a obj subdirectory rule in:
    Unfortunately, arm64 also references the EFI libstub via:
    libs-$(CONFIG_EFI_STUB) += drivers/firmware/efi/libstub/
    If we're unlucky, the kernel build system can enter libstub via two
    simultaneous threads resulting in build failures such as:
    fixdep: error opening depfile: drivers/firmware/efi/libstub/.efi-stub-helper.o.d: No such file or directory
    scripts/Makefile.build:257: recipe for target 'drivers/firmware/efi/libstub/efi-stub-helper.o' failed
    make[1]: *** [drivers/firmware/efi/libstub/efi-stub-helper.o] Error 2
    Makefile:939: recipe for target 'drivers/firmware/efi/libstub' failed
    make: *** [drivers/firmware/efi/libstub] Error 2
    make: *** Waiting for unfinished jobs....
    This patch adjusts the arm64 Makefile to reference the compiled library
    explicitly (as is currently done in x86), rather than the directory.
