I added MIDAS Makefile rules for building ARM binaries: "make linuxarm" and "make cleanarm" will create 
(and clean) object files, libraries and executables under "linux-arm" using the TI Sitara ARM SDK or the 
Yocto SDK ARM cross-compilers (GCC 4.7.x and 4.8.x respectively). (Makefile rules for building PPC 
binaries have existed for years).

The hardware we have at TRIUMF are "ARMv7" machines - TI Sitara 335x CPUs (google mityarm) and Altera 
Cyclone 5 FPGA ARM (google sockit). (as opposed to the ARMv5 CPU on the RaspberryPi). The software 
binary API standard settled by Fedora Linux is "hard float" (as opposed to "soft float" used by older SDKs).

So "ARMv7 hard float" is what we intend to use at TRIUMF, but ARMv5 and soft-float should also work ok, 
so please report successes and/or problems to this forum.

K.O.
