Cross compilation support (#709) * build: add cross-compilation support to make Set CROSS_COMPILE when running make to use the selected cross compilation toolchain, such as arm-linux-gnueabihf, or aarch64-linux-gnu. Testing requires the presence of qemu - 'qemu-$(ARCH)' will be executed, where ARCH is the first part of the toolchain triplet. * build: add cross-compilation support to cmake If C_COMPILER/CXX_COMPILER/CC/CXX are found to have cross-compilation triplets in front of the compiler, then qemu will be used to execute the tests. * CI: add arm-linux-gnueabihf-gcc builder to Travis The version of qemu available in Ubuntu trusty (as provided by Travis) appears to have a bug in qemu-aarch64, which leads to the compatibility tests failing on some inputs, erroneously rejecting the input as corrupt. Once Travis supports xenial, we could add an aarch64-gnu-linux-gcc builder as well. * CI: propagate cmake errors out of .travis.sh Seems like even if cmake fails, the error isn't picked up by Travis.
