First, build your target binutils and install them.

Put the /bin dir that includes all the target binutils in your PATH.

configure gcc like this:

  $ /home/aph/gcc/trunk/configure --prefix=/home/aph/x-arm/install --target=arm-linux --with-sysroot=/home/aph/x-arm/chroot-arm/ --with-headers=/home/aph/x-arm/chroot-arm/usr/include/ --prefix=/home/aph/x-arm/install2 --disable-libssp --disable-libgomp --disable-libmudflap --enable-libgcj --disable-multilib --disable-static --disable-sjlj-exceptions --enable-languages=c,c++,java

Do not configure gcc in its srcdir.

make and make install
