Unable to build RKI

[Deval Shah]

Hello,
I am following this tutorial for raspberry pi B+.
http://alanstechnotes.blogspot.in/2013/03/setting-up-rtems-development.html
I am able to run ticker program on raspberry pi, but unable to build rki.

make command:
make ARCH=arm-rtems4.11 BSP=raspberrypi
RTEMS_TOOL_BASE=$HOME/development/rtems/compiler/4.11/
RTEMS_BSP_BASE=$HOME/development/rtems/build-rtems-rpi


make gives error at this command:

arm-rtems4.11-gcc -march=armv7-a -mthumb -mfpu=neon -mfloat-abi=hard
-mtune=cortex-a7 --pipe -B/opt/rtems-4.11/arm-rtems4.11/raspberrypi/lib
-specs bsp_specs -qrtems -Wall -o

legacy-build/arm-rtems4.11-raspberrypi/tarfile.o -lm


some part of error from make command:

error search on google shows some issue with soft floating points and hard
floating points. I am unable to understand that. Any help ??
