Sometimes, AC_C_BIGENDIAN can determine endianness from constants defined
in header files and doesn't actually have to run a program.

Your method would be the one to use in other setups, but as I pointed
out in an accompanying mail, the config.frag files are the preferred
way of doing the same thing in Kaffe.

The links to md.? are already made by the configure script.
They depends on the host setting (--host).  There is no target setting
in Kaffe.  According to the info page on autoconf, the target type
is the type of system for which any compiler tools in the package will
produce code.  There aren't any compiler tools (well, maybe kaffeh--
but that's not what we're talking about here) in the Kaffe package,
hence no --target.
