Maciej W. Rozycki fe7dd93db3 m68k: Use an autoconf template to produce `preconfigure'
Switch to using AC_MSG_ERROR rather than `echo' and `exit' directly for
error handling.  Owing to the lack of any kind of error annotation it
makes it difficult to spot the message in the flood in a parallel build
and neither it is logged in `config.log'.
