gcc-plugins: fix build condition of SANCOV plugin
Since commit d677a4d60193 ("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.
Fixes: d677a4d60193 ("Makefile: support flag -fsanitizer-coverage=trace-cmp")
