Currently, we need a patch either way, as --subsystem:xbox isn't allowed, 
and ld doesn't accept numbers either (--subsystem:14).  It's just rather 
dangerous to leave EXEs floating around that executing could do who knows 
what to Windows.  Setting subsystem 14 causes an error when trying to run 
one.

I guess so...  I suppose --target=i686-pc-mingw32 --program-prefix=xbox- is 
enough, with a patch for --subsystem:xbox support.

For someone that understands ld, probably not.  But I don't, and XBE stuff 
is a little weird, with a million options.

XBE is most like PE, as you probably guessed.  However, to correctly 
implement XBE requires the SHA-1 hash algorithm, which is a significant 
addition.
