When building vmlinuz.efi with CONFIG_EFI_ZBOOT enabled, '__lshrdi3()'
is also needed to fix yet another link error observed when building
riscv32 and loongarch32 images:

riscv32-linux-gnu-ld: drivers/firmware/efi/libstub/lib-cmdline.stub.o: in function `__efistub_.L49':

And since both riscv64 and loongarch64 can have CONFIG_EFI_ZBOOT but
doesn't need these library routines, rely on CONFIG_32BIT to manage
linking of lib-ashldi3.o and lib-lshrdi3.o on 32-bit variants only.
