Thanks.  I have now used --enable-add-ons=$src/eglibc/ports, and configure
does not complain anymore about --with-cpu=e500, but compilation still fails
with

    In file included from ../sysdeps/powerpc/powerpc32/fpu/s_isnan.c:1:
    ../sysdeps/powerpc/fpu/s_isnan.c:59: warning: conflicting types for built-in function `isnanf'

Does that mean that it is impossible to compile the eglibc svn tree as-is for
e500 ?

I will try by copying the ports/ directory into the libc/ directory, but that
makes the use of the svn version more difficult.
