Not quite.

I created the binutils

wget http://ftp.gnu.org/gnu/binutils/binutils-2.18.tar.bz2
tar xvjf binutils-2.18.tar.bz2
cd binutils-2.18
  ./configure --prefix=/home/luca/crossbinutils --target=armel-linux
make
make install

I created a ppcarm with compiler cycle:
make clean compiler_cycle OS_TARGET=linux CPU_TARGET=arm 
BINUTILSPREFIX=/home/luca/crossbinutils/bin/armel-linux- OPT=-dFPC_ARMEL 
FPC=/scratchbox/users/luca/home/luca/fpc/lib/fpc/2.3.1/ppc386

But the resulting ppcarm doesn't work under scratchbox:

[sbox-CHINOOK_ARMEL: ~/fpc-svn] > make clean zipinstall OPT=-dFPC_ARMEL 
FPC=./ppcarm
qemu: uncaught target signal 6 (Aborted) - exiting
qemu: uncaught target signal 6 (Aborted) - exiting

Makefile:199: *** The Makefile doesn't support target syscall-Error:, 
please run fpcmake first.  Stop.
[sbox-CHINOOK_ARMEL: ~/fpc-svn] > ./ppcarm
Error: unimplemented syscall 90004c
qemu: uncaught target signal 6 (Aborted) - exiting


If I try to run in in the tablet:
~ $ ./ppcarm
Illegal instruction

I guess I'll stick to i386 for a while ;-)
