rc on MkLinux (or anything with a ppc and gcc)

[Brian Ward]

I have a couple of hints for anyone wanting to use rc on this config.
First and foremost, don't use the libc that comes with the DR2, get the
newest from the Updates/libs directory. Among other things, readdir() was
broken in the old one.

Second, they did something strange with va_list for the PowerPC gcc
compiler- made it into a one-element array for some reason which I'd rather
not know. So, to get past that (print.c doesn't compile), use a stupid hack
like the one in the patch I'm appending to the end of this message.

Third, use /usr/src/asm/signal.h for sigmsgs.c, as usual with Linux.

Anyway, as usual, thanks to Byron and everyone else who's done work on the
port, it's really a better life when you don't have to use something which
I'd prefer not to think of for a shell. Really.
