[cross compiling gpsd for ARM] packet.c x86_64-linux-gnu-gcc: not found ?

[Eddie Sutton]

 At the start, it looks like everything is building fine using arm-poky-linux-gnueabi-gcc to target embedded Linux on ARM.

The second time it starts to build packet.c ( building packet_ffi_extension? ), the build switches to the host's native compiler x86_64-linux-gnu-gcc which while installed in the build host, cannot be found in the cross build environment.

I cannot undersatnd why the build switches to using the host's native compiler x86_64-linux-gnu-gcc instead of continuing to use arm-poky-linux-gnueabi-gcc.  I did not see any obvious work-arounds in the SConstruct file.

Any tips or suggestions are much appreciated.
