Chris, It looks like _libelf_config.h has the defines for an ARM host on FreeBSD, but for linux it includes "native-elf-format.h". It looks like this file is produced with the native-elf-format binary, which produces this output: pi@raspberrypi ~/rtems-tools.git/rtemstoolkit/elftoolchain/common $ ./native-elf-format /* Generated by native-elf-format on Tue Feb 10 03:33:38 UTC 2015 */ #define ELFTC_CLASS ELFCLASS32 #define ELFTC_ARCH unknown #define ELFTC_BYTEORDER ELFDATA2LSB pi@raspberrypi ~/rtems-tools.git/rtemstoolkit/elftoolchain/common $
So the #define ELFTC_ARCH unknown statement causes the compile error. I can dig into this later, it's not a big deal, I just want to make my RPI 2 serve as a development host for my RPI 1 :) As for the Linux on RPI 2, I think they are using the same Raspbian distro, so this probably happens on the RPI 1 as well.
