# Check that the external toolchain supports C++
check_arm_abi builds a test C file to check that the toolchain is working correctly, with the output redirected to /dev/null. However, some toolchains (OSELAS 2014.12.0, for instance) foolishly append ".gdb" to the output filename for an intermediate file, causing an attempt to write to /dev/null.gdb, which obviously fails. Fix this by adding changing the output to a temporary file, which is later removed along with any other "suffixed" files. Suggested-by: "Yann E.
