I would expect that configuration with --disable-networking then
problem cold go away. What toolchain (NewLib, GCC) do you use?
The missing file is part of the RTEMS

rtems/cpukit/libnetworking/netinet/in.h

it is preinstalled during build to

build/arm-raspberrypi2/rtems/arm-rtems4.12/raspberrypi2/lib/include/netinet/in.h

and finally installed to 

/opt/rtems4.12/arm-rtems4.12/raspberrypi/lib/include/netinet/in.h

As for the actual mainline, I have build RPi 2 with my latest
patches setup successfully. I used next configuration

../../../git/rtems/configure --target=arm-rtems4.12 --prefix=/opt/rtems4.12 \
  --enable-rtems-inlines --disable-multiprocessing --enable-cxx \
  --enable-rdbg --enable-maintainer-mode --enable-tests=samples \
  --enable-networking --enable-posix --disable-itron --disable-ada \
  --disable-expada --disable-multilib --disable-docs \
  --enable-rtemsbsp="raspberrypi2"

I have tested on HW only RPi1 build, but I have managed/hacked my build
of QEMU 2.6 to run RPi2 ticker image with arm-none-eabi-gdb used for
load of image to the emulator. The ticker run through whole initialization
and prints the time zero messages. But then it stalls because RTEMS
use of timer seems to be inncompatible with QEMU RPi2 limited support
still. I hope that my RTEMS RPi BSP updates should work well
with real RPi2 HW and even graphic console should work same as on RPi1
when enabled by config.txt.

It would be great if my series can be tested and ACKed for mainline
integration.

Best wishes,

               Pavel
