[PATCH v2 1/2] kbuild: replace cc-name test with CONFIG_CC_IS_CLANG

2018-10-30 Thread Masahiro Yamada
Evaluating cc-name invokes the compiler every time even when you are not compiling anything, like 'make help'. This is not efficient. The compiler type has been already detected in the Kconfig stage. Use CONFIG_CC_IS_CLANG, instead. Signed-off-by: Masahiro Yamada Acked-by: Michael Ellerman
