Anyone has enough knowledge about IRIX to know a way of matching IRIX
binaries reliabily?

Looking at IRIX 6.5 binaries ELF sections, I can see that both static
and dynamic programs have a .MIPS.options section. I'd like to be sure
that we don't find this section in non IRIX binaries on MIPS. I've
checked Linux and NetBSD, what other OS could be checked?
