Trouble building GCC 2.95.2 on intel Linux as cross compiler for PPC

[Phil Karn]

When I try to build GCC 2.95.2 as a cross compiler for ppc-eabi, I get
the following errors. The host is a Debian GNU/Linux system running
the "frozen" release of potato, which has gcc 2.95.2.

I have already built and installed binutils-2.10 for ppc-eabi without
trouble. Both the binutils and gcc builds are done in directories
separate from the source trees.

I have a full script of the tarball extraction and build attempt, if
anyone wants to see it.
