Cross-compiling with GCC

I'm currently trying to make up MIPS executables, for the r3000 CPU, under
x86/Linux (recently upgraded to rh5.2 distrib).
When i type:
gcc (or egcs) -mcpu=r3000 hello.c
i get told that cpu=r3000 is an invalid option. (although it's in the manual
pages.)
When I try
gcc -b MIPS -mcpu=r3000 hello.c
I get told that it cannot find/exec cpp
(cpp is present, under a i386-linux directory though, but I guess by saying
i want the machine type to be MIPS, it's looking under /usr/lib/MIPS-linux/
instead, which doesn't exist)

The question is thus - how do i cross-compile? Do I need to get a different
install of MIPS GCC with x86 executables? Or do I just need a correct
compiling switch?
Can any gcc gurus help?

Yours,
Toby
(goes back to reading man pages)
