That file should not be built when cross-compiling.  This means that
configure has not entered cross-compilation mode.  This is probably
because you have only specified --host (the host is what you are
building on, not the target)  The autoconf recommended way to enable
cross-compilation is to specify both --build (the target) and --host
(the host machine).  If they are different, cross-compilation mode is
enabled, and no runtime checks are performed.
