Thank you. This will be very useful. I am trying this on RHEL 5.8 with:

MXE_SYSTEM := gnu-linux
MXE_NATIVE_BUILD := yes
USE_SYTEM_GCC := no

But I get the following error while building gcc:

Is this supposed to work? If so I can investigate further. Otherwise
(and in the meantime) I will try to use the system GCC (version 4.1.2 in
this case).

Next error I am looking into is in build-only-arpack:
configure: error: Cannot find BLAS libraries

Somehow I ended up building Octave on really old and new systems at the
same time...
