kbuild,objtool: Defer objtool validation step for CONFIG_KLP_BUILD
In preparation for klp-build, defer objtool validation for
CONFIG_KLP_BUILD kernels until the final pre-link archive (e.g.,
vmlinux.o, module-foo.o) is built. This will simplify the process of
generating livepatch modules.
Delayed objtool is generally preferred anyway, and is already standard
for IBT and LTO. Eventually the per-translation-unit mode will be
phased out.
