The other possibility is that you didn't configure right.  My configure line is

/home/aph/gcc/ubuntu/gcc-4_2-branch/configure \
--target=arm-linux \
--with-sysroot=/home/aph/x-arm/chroot-arm/ \
--with-headers=/home/aph/x-arm/chroot-arm/usr/include/ \
--prefix=/home/aph/ubuntu/gcc-4_2-branch/install \
--disable-libssp \
--disable-libgomp \
--disable-libmudflap \
--enable-libgcj \
--disable-multilib \
--disable-static \
--disable-sjlj-exceptions \
--enable-languages=c,c++,java
