kbuild: include Makefile.compiler only when compiler is needed
Since commit f2f02ebd8f38 ("kbuild: improve cc-option to clean up all temporary files"), running 'make kernelversion' in a read-only source tree emits a bunch of warnings: mkdir: cannot create directory '.tmp_12345': Permission denied No-build targets such as kernelversion, clean, help, etc. do not need to evaluate $(call cc-option,) or friends. Skip Makefile.compiler so $(call cc-option,) becomes no-op. This not only fixes the warnings, but also runs non-build targets much faster. Basically, all installation targets should also be non-build targets. Unfortunately, vdso_install requires the compiler because it builds vdso before installation. This is a problem that must be fixed by a separate patch. Reported-by: Israel Tsadok <> Signed-off-by: Masahiro Yamada <>
