Support Minix 2.0.2 Binaries

[DoctorWkt]

Chris, there's a port of MINIX 2.0.2 to the Atari ST here. It's interesting as there are three working C compilers: ACK (but with ANSI C support), Sozobon and c68. It looks like the system calls are identical, but the magic number in all the binaries is 0x0b100301. I can't see any split-I/D binaries, so in my fork I quickly added a test for this magic number as well.

The cat binary works, but the ls binary complains about the command-line arguments. I'll compile up some test programs and see what the problem is. Hopefully we can easily support the 2.0.2 binaries.

Oh, interesting! I think there may be some other substantial differences too in things like signal handling, but it'd definitely be great to support a wider set of binaries. I've mostly stuck to 1.5 because I find it very tractable and it's what I have the most experience with, but if 2.0 support doesn't mean breaking 1.5 support it'd be awesome.

I'll hold off on closing this as part of #15 since there may be more we need to do to actually support MINIX 2.0.2.

Absolutely!
