The do_space function is defined in ways that are useful, or that fail immediately, depending on various macros. When it fails immediately, the filesystem space.cc tests fail noisily, but the fail is entirely expected.
Define HAVE_SPACE in the space.cc tests, according to the macros that select implementations of do_space, and use it to skip tests that are expected to fail. Regstrapped on x86_64-linux-gnu, also tested with a cross to aarch64-rtems6.
