gcc-plugins: fix build condition of SANCOV plugin
Since commit d677a4d6 ("Makefile: support flag -fsanitizer-coverage=trace-cmp"), you miss to build the SANCOV plugin under some circumstances. CONFIG_KCOV=y CONFIG_KCOV_ENABLE_COMPARISONS=y Your compiler does not support -fsanitize-coverage=trace-pc Your compiler does not support -fsanitize-coverage=trace-cmp Under this condition, $(CFLAGS_KCOV) is not empty but contains a space, so the following ifeq-conditional is false. ifeq ($(CFLAGS_KCOV),) Then, scripts/Makefile.gcc-plugins misses to add sancov_plugin.so to gcc-plugin-y while the SANCOV plugin is necessary as an alternative means.
