A quick guess is that you use your host gcc and not your target gcc. You most likely have to set CROSS_COMPILE=... Try with "make V=1" to see the exact gcc command line.

I tried make V=1 but the loads of info was given for the things that went right but nothing noticeable where the error is. I've attached my arch/arm/Makefile. My build, host and target are on same system. i am emulating the board with Qemu. The process is very conventional. I've mounted my rootfs with -o loop and kernel and extra modules go there with INSTALL_MOD_PATH and INSTALL_MOD_DIR.
