Assuming that you have binutils compiled and installed for arm-linux, in
/opt/test-cross-gcc-arm-linux

and your working directory layout is :

./build        -> for building
./gcc          -> gcc source
./genattrtab.i -> for testing


You can do this :


export PATH=/opt/test-cross-gcc-arm-linux/bin:$PATH
cd build
../gcc/configure --prefix=/opt/test-cross-gcc-arm-linux --target=arm-linux --with-cpu=xscale --enable-languages=c
make
gcc/cc1 -fpreprocessed ../genattrtab.i -quiet -dumpbase genattrtab.c -auxbase-strip genattrtab.o -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Werror -Wno-error -version -fno-common -o 
genattrtab.s

Results in :

GNU C version 3.5-tree-ssa 20030516 (merged 20030511) (arm-linux)
	compiled by GNU C version 3.0.4.

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.



Note : In my testsetup, I have in /opt/test-cross-gcc-arm-linux, besides binutils,
 also glibc and a cross-arm-linux gcc-3.0.4 compiler installed.
 This may influence the reproducability of this procedure. (headers, libraries, ...)
