Since commit 805b2e1d42 ("kbuild: include Makefile.compiler only when
compiler is needed"), "make ARCH=arm64 (modules_)install" shows a false
positive warning.
Move the ld-option test to Kconfig, so that the result can be stored in
the .config file, avoiding multiple-time evaluations in the build and
installation time.
