[LLVMdev] build errors while cross compiling llvm-gcc for ARM

my g++-cross was configured with following parameters:

./configure --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu
--target=armv7fl-montavista-linux-gnueabi --enable-cross
--with-build-sysroot=/home/arm_v7_vfp_le/target/ --enable-shared
--enable-languages=c,c++ --with-as=/home/arm_v7_vfp_le/bin/arm_v7_vfp_le-as
--with-ld=/home/arm_v7_vfp_le/bin/arm_v7_vfp_le-ld --enable-checking=release
--disable-multilib --enable-llvm=/home/Desktop/Sanjeev/LLVM/llvm-2.7
--enable-clocale=gnu --with-cpu=cortex-a8 --with-interwork
--with-arch=armv7-a --with-mode=arm --with-tune=cortex-a8 --with-fpu=vfp3
--disable-bootstrap --disable-libmudflap --disable-libssp

But any file e.g. a.c compiled with g++-cross if I try to link using ld-new,
I get error
ld-new libs a.o -o binary
a.o : incompatible object file

ld-new works only with those objects which are compiled using native gcc but
doesn't work for cross-compiler gcc/arm.
