Does not build with most recent gcc-arm-none-eabi 4.9.3 x64 #21

Closed shulter closed 8 years ago

Tested with ubuntu wily x64, a standard apt-get gcc-arm-none-eabi yields version 4.9.3.

/usr/lib/gcc/arm-none-eabi/4.9.3/../../../arm-none-eabi/bin/ld: error: hv_firmware.o: Conflicting CPU architectures 13/0
/usr/lib/gcc/arm-none-eabi/4.9.3/../../../arm-none-eabi/bin/ld: failed to merge target specific data of file hv_firmware.o
collect2: error: ld returned 1 exit status
Makefile:72: recipe for target 'main.elf' failed
make: *** [main.elf] Error 1

FYI: Makefile from https://github.com/synthetos/g2 downloads an older gcc-arm-none-eabi in 32bit, hard linking to it for compilation, then libz32 is needed on x64 systems.
