you need to set the cross toolchain environment first and specify sysroot
and ABI options, i.e.:

 $ . /opt/eldk-5.8/armv7a-hf/environment-setup-armv7ahf-vfp-neon-linux-gnueabi
 $ arm-linux-gnueabi-gcc --sysroot=/opt/eldk-5.8/armv7a-hf/sysroots/armv7ahf-vfp-neon-linux-gnueabi \
   -mfloat-abi=hard -o x x.c

should work.

Or just run

  $CC -o x x.c


Best regards,
