GCC binaries for IRIX, HP-UX, Tru64

[Tobias Nygren <tnn%NetBSD.org@localhost>]

I've uploaded[1] gcc-4.2.3 binary builds for:
 - IRIX 6.5 (n32)
 - HP-UX 11.11 (32)
 - Tru64 5.1

They should come in handy for anyone who wants to try out
pkgsrc. Builds targeted for other ABIs can be made on demand.
Please see the file README.gcc for installation instructions.

Have fun,
-Tobias
