[Devel] [PATCH hci-8.1 2/2] ms/kbuild: move GCOV flags to scripts/Makefile.gcov

[no-reply at sashiko.virtuozzo.com]

>  * split the CFLAGS_GCOV block out of the top-level Makefile into
>    scripts/Makefile.gcov
>  * include it via include-$(CONFIG_GCOV_KERNEL) like neighbour
>    KASAN/KCOV/UBSAN makefiles do
>  * keep the include before scripts/Makefile.gcc-plugins: the try-run
>    must not get -fplugin= options, plugins do not exist on clean builds
> 
> CFLAGS_GCOV is no longer defined when CONFIG_GCOV_KERNEL is off:
>  * its user in scripts/Makefile.lib is guarded by the CONFIG_GCOV_KERNEL
>  * in i915/xe header an empty value is harmless
> 
> The try-run compiler invocations also stop running on builds without
> GCOV.
