We actually have to change it in the future. Autoconf 2.5x will have
target_alias set to nothing unless --target is explicitly set, unlike
autoconf 2.13, that sets it to the implied value if it's not given in
the command line. I wish we could avoid introducing new
incompatibilities now that we're looking into moving to autoconf 2.5x.
