Well you say your target is powerpc-linux, but you also say 
--with-newlib.  Is that really correct?  I do similar mips builds all 
the time without problem, but I also specify --with-sysroot= so that the 
  system libraries and header files are found.

If you are trying to bootstrap a toolchain, you might give Crosstool a 
try.  It takes care of specifying all the fiddly options needed to 
bootstrap a toolchain.
