This makes no sense...how/why did you use an rpm of egcs to build
binutils from source?  That doesn't really make any sense.  Could you
please indicate what exact files you are using and where you got them
from?  If you are applying patches, please mention those as well.

This is not needed to build either gcc or the kernel.

What are you doing with both an rpm and a source tarball?  An RPM is
surely not a patch.  Also, it is traditional to build gcc outside the
source directory; it's possible that that is a source of trouble.  The
random "3D" in your output there is either another source of trouble
or an artifact of your mailer; in either case it should be fixed.

If you are having trouble building a cross-toolchain, you might
consider getting make-cross from
ftp://oss.sgi.com/pub/linux/mips/mips-linux/simple/crossdev - it takes
most of the hard parts out of it.  There's also a source toolchain
there that seems to work fairly well; it compiles glibc, for example,
which no version of egcs 1.1.2 I have seen will.  Of course, if you
want to use different versions you can do that as well.
