You are wrong.  Obviously such a test can not be run when cross compiling,
but that is true for all tests where you need to run a program (note that
the above is meant as an actual C program doing a mkdir() and a read()).

And when cross compiling, either the user has to specify the test result in
a config cache, or grep needs to rely on host_os to determine the default
for known systems.

This is all canonical, and you should really have known this if you worry
about cross-compilation (as you seem to do).

Thanks,
Marcus
