MIPS toolchain

[James Jones]

Could you provide steps for building cross tool chain. I have not done it so long. I have tried many different versions of howtos but all have fallen short or I am not understanding. I need a toolchain for target 'mips-unknown-elf'.

However, the result is a pretty sane compiler, linker, etc, setup for the MIPS of your choice (we tend to use mips64eb).

In fact, there are some toolchain bugs I'm running into that manifest only in the SDE toolchain and not the FreeBSD toolchain.  (Mind you, Philip has commented that in building Uboot for MIPS, he's found FreeBSD bugs that don't appear in the SDE toolchain, so mileage varies).
