Make sure you are using arm-eabi-gcc and arm-eabi-binutils, otherwise
file format and compiler switches for target are invalid as you
probably use host toolchain (not the target toolchain). At the moment
there is a conflict between host binutils and arm-eabi-binutils
packages (some localization files related conflict), so I also wait
for this to get resolved :-) When you use proper compiler and utils it
will work and switches become available for that target :-)

Best regards :-)
