Is there a glibc-ports-3.3.5 directory anywhere in the
source or build directories?
  cd /home/peter/work/cvs-logic/logic/ColdFire/LinuxTools/crosstool
  find . -name glibc-ports-3.3.5

Does that string occur anywhere in any file in those directories?
  find . -type f | xargs grep glibc-ports-3.3.5

If that doesn't help, try figuring out the smallest shell
script to reproduce the error, e.g.
  export PATH=...
  cd /home/peter/work/cvs-logic/logic/ColdFire/LinuxTools/crosstool/build/m68k-linux/gcc-3.4.3-glibc-2.3.5/build-glibc
  make lib
If that reproduces it, then try to figure out a smaller target
that also reproduces it, e.g.
  export PATH=...
  cd /home/peter/work/cvs-logic/logic/ColdFire/LinuxTools/crosstool/build/m68k-linux/gcc-3.4.3-glibc-2.3.5/build-glibc
  make libc_pic.a
If that also reproduces it, then maybe you have a chance of
interpreting make's verbose output then.

And then there's always understanding the Makefile structure better -
which is a bit of an adventure with glibc.  It uses
lots of features of gnu make I'd never seen used before.
