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.
