Let's make it possible to install the sysroot directly in the test directory. It's not big and even benefits from being copied by arch so that it's easier to switch between archs if needed. The new "sysroot" target does this, it just calls "headers_standalone" from nolibc to install the sysroot right here. Signed-off-by: Willy Tarreau Signed-off-by: Paul E.
