GNU Autoconf has supported the option for packages to specify a fallback
that avoids the need to run a cross-compiled binary; this is done by
supplying the fourth argument to AC_RUN_IFELSE (present since Autoconf
2.55 in 2002):
https://www.gnu.org/software/autoconf/manual/autoconf.html#Runtime

It is not Autoconf's fault if packages use this macro incorrectly.  I
will grant that not all packages that use autoconf are designed for
cross-compilation, but that is the flaw of such packages, and not of
autoconf.

Further complaints or suggestions about autoconf are probably better
directed to the autoconf list instead of the tar list.
