Maybe I'm missing something here. How can you run a program at
build-time, in a cross-compiler environment? At that moment you don't
have access to the target, and you can't rely on the outcome of a
host-test to give information on the behavior of the target... (even
regardless of the filesystem argument Ralf raised).
