Subject[PATCH 4/9] kbuild: add a new kselftest_install make target to install selftests
Date
Add a new make target to install kernel selftests. This new target will
build and install selftests.

The default is just $(objtree)/selftests. This is preferable to
something based on $(INSTALL_MOD_PATH) (which defaults to /), as it
allows a normal user to install the tests. This is similar to the
default behaviour of make headers_install.

Therefore the most basic usage is:

$ make kselftests_install
$ ./selftests/all.sh

To install elsewhere use:

$ make kselftests_install INSTALL_SELFTESTS_PATH=/some/where
$ /some/where/all.sh
