ARM Toolchain: search compiler in PATH Add CMake target for strip since these changes break adb_upload_to_bebop. GCC users should add the cross compiler bin path to PATH (location of arm-linux-gnueabihf-g++). Clang user should do the following: * set CMAKE_CXX_COMPILER to clang++ by providing -DCMAKE_CXX_COMPILER=clang++ to cmake * get GCC cross compiler - needed because Clang does not ship a CRT * create a symlink for clang and clang++ in GCC cross compiler bin dir. * add GCC bin dir to PATH Signed-off-by: Nicolae Rosia <nicolae.rosia@gmail.com>
