From: Mickaël Salaün <mic@xxxxxxxxxxx>
commit de3ee3f63400a23954e7c1ad1cb8c20f29ab6fe3 upstream.
This change enables to extend CFLAGS and LDFLAGS from command line, e.g.
to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static
USERCFLAGS and USERLDFLAGS are documented in
Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst
This should be backported (down to 5.10) to improve previous kernel
versions testing as well.
