I noticed we're invoking $(CC) via $(shell) more than once to check the version. Let's reuse the first string captured in $CC_VERSION_TEXT.
Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> [masahiro.yamada: CC_VERSION_TEXT is assigned by = instead of :=, so this $(shell ) is evaluated multiple times anyway. The number of $(CC) invocations will be still the same. Replacing 'grep' with the built-in $(findstring ) will give real performance benefit.] Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
