So we need something like AC_MSG_CROSS_WARN that basically does
_AC_ECHO_N([[CROSS] ])
_AC_ECHO_N([[CROSS] ], AS_MESSAGE_LOG_FD)
and maybe outputs a warning at the end of configure, that some values
needed to be guessed due to cross-compiling?

Having a global marker one can look for in config.log would ease
cross-compiling, as nowadays everybody does it his way. Maybe
AC_MSG_CROSS_WARN could also output to config.log, which cache value would
have to be set.

Anyway, if you want me to let this test just fail instead, just tell me.

Yours, Rüdiger.
