You should not need to set CC and CXX to build, and these are probably
causing your build failures...  I don't have a RPi2, but the instructions
at: https://wiki.freebsd.org/FreeBSD/arm/Raspberry%20Pi%202%20image
should be enough, notice the following:
 # make TARGET_ARCH=armv6 UBLDR_LOADADDR=0x2000000 buildworld
 # make TARGET_ARCH=armv6 KERNCONF=RPI2 buildkernel

Once you have those built, then comes how to install it... One method
is to do:
make TARGET_ARCH=argv6 installworld DESTDIR=<someemptydir> -DNO_ROOT
tar -czf rpi2.tgz @<someemptydir>/METALOG

which you can extract over, or follow the instructions on the wiki page
for building a new image...

Hope this helps...
