Alright, lets see if I'm looking at this correctly. SDL seems strange.

stbmac:work Michael$ ls
total 0
0 SDL-1.2.14/		0 SDL-1.2.14-i386/	0 SDL-1.2.14-ppc/
stbmac:work Michael$ pwd
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_libsdl/work

If I understand what's going on:
1. SDL-1.2.14 is where it was unpacked and patched.
2. The -386 and -ppc are copies that each ran configure separately.
3. SDL's SDL_config.h before configure looks good, and completely
different than SDL_config.h after configure.

4. The problem is that BYTEORDER is constant afterwards, and wrong on PPC.

Which is the better solution?
A: Fix BYTEORDER, so that the two files are different in the two
configurations, or
B: Delete BYTEORDER, and let other ifdef's fix it at compile time (the
config files are then identical)

After I make this edit, how do I make sure that MacPorts doesn't ever
decide to re-run configure?
