MIPS: Use an autoconf template to produce `preconfigure'
Avoid fiddling with autoconf internals and use AC_DEFINE_UNQUOTED to define macros in the configuration headers rather than handcoding an equivalent shell sequence with the use of the `as_echo' undocumented variable. Similarly use AC_MSG_ERROR for error handling rather than the internal undocumented `as_fn_error' variable. Switch to using 1 as the exit code as it makes no sense to refer $? in the contexts involved, it's not a command failure handled there.
