Libc 2.2 cross build problem, i386 -> powerpc w/o FPU

[kimt]

I'm trying to cross-build a glibc for a powerpc without an FPU
available.  My build machine is i386-linux, the target is a
powerpc-linux machine.  I run configure as follows:

# ... this is the linux include directory equivalent to /usr/include
HDRDIR=`pwd`/../../../include

configure --target=powerpc-linux \
--with-headers=${HDRDIR} \
--with-gnu-as --with-gnu-ld \
--enable-add-ons=crypt,linuxthreads \
--disable-sanity-checks --without-fp \
--build=i686-linux --host=powerpc-linux

and start a make.  Much later, it gets an error: 

make  -C math others

There does seem to be an fenv_libc.h file in sysdeps/powerpc/fpu, but
it is not in one of the -I specs.  I'm not sure where to proceed, but
any pointers would be helpfull.

P.S. We've also tried this with glibc-2.1.3, but ran into some other
problem.
