Thanks Stefan and Marc,
The -m64 gcc option suggested by Marc worked as well:
make[5]: Nothing to be done for `install'.
make[2]: Nothing to be done for `install-target'.
finished target cross-gdb.install
------------------------------
target: cross-gdb.install.post
------------------------------
finished target cross-gdb.install.post
finished target world.targetinstall
******************
I already compiled a simple c++ HelloWorld for my powerpc smartcam.
Now I'm tweaking all those missing libs on the target.
Thanks again,
Markus

Hi,
in our compiler build script for coreboot we used the following to get
GMP and mpfr working on both OS X 10.5 and 10.6..
Note the hard code on ABI=32 (because the configure script misdetects
this on 10.5) and the -force_cpusubtype_ALL for MPFR

GMP:
[..]
if [ `uname` = "Darwin" ]; then
# generally the OS X compiler can create x64 binaries.
# Per default it generated i386 binaries in 10.5 and x64
# binaries in 10.6 (even if the kernel is 32bit)
# For some weird reason, 10.5 autodetects an ABI=64 though
# so we're setting the ABI explicitly here.
OPTIONS="ABI=32"
touch .architecture_check.c
gcc .architecture_check.c -c -o .architecture_check.o
ARCH=`file .architecture_check.o |cut -f5 -d\ `
test "$ARCH" = "x86_64" && OPTIONS="ABI=64"
rm .architecture_check.c .architecture_check.o

MPFR:
