  Doh.  I misread this; I see now that what you mean is you wanted a native
compiler on the target.

  So, this should have worked.  Did you perhaps re-build in the same directory
that you had already configured the cross-compiler in without first running
"make clean" perhaps?  Was the powerpc-linux cross compiler placed in your
$PATH setting, so that configure could find the powerpc-linux-gcc executable?
