I didn't have any problem with gcc-2.95.*. Never tried gcc-2.8.1
because it is too old to be useful anyway.

Doesn't matter, it's just a make subtlety that doesn't break anyway.

You shouldn't change CROSS_COMPILE at this stage because you can't
build the kernel anyway. This kernel is only needed to supply gcc and
libc with system header files.

Possible that the standard linux tree is broken for ARM, but you should
*always* apply Russell's patch on top of it (patch-2.4.5-rmk3.gz is the
latest at time of writing).

I don't have control over it (Phil? Wookey?).

I keep on saying this to people with toolchain problems: Why don't you
just download a precompiled toolchain?
And if you do want to build a toolchain yourself: first try to build
one *exactly* according to the documentation before you start
experimenting.

Why arm-coff? All modern arm-linux system use ELF, so you should use an
arm-linux target (which automatically selects ELF).

Just do:
make lart_config
make oldconfig
make dep
