I use /dev/null, which will never be a directory.

There's no way to disable sysroot; setting it to empty is the same as
not setting it at all, i.e. use the host's libraries.

A relative path may be a valid sysroot; GDB will search from its
current directory (there's no special check for absolute paths).
