Building RTEMS for BeagleBone Black failed

I'm getting the same redefine error as my other attempts on FreeBSD.

I went back to the drawing board and started from the top in the
documentation using the SPARC build. The following is what I have done
so far. The base path is ~/Git (/usr/home/russellh/Git)

mkdir -p rtems/4.12 && cd rtems/4.12

git clone git:// rsb
cd rsb
./source-builder/sb-check #check OK
cd rtems
--prefix=/usr/home/russellh/Git/rtems/4.12 4.12/rtems-sparc

Interestingly the re-defined values are different...

I'm heading out for a bit but will create a ticket when I get back if
so desired. I will try this on Debian later too.
