xcompile: test if gcc is really available

Just because an 'as' with a certain prefix is available does not guarantee
    that a 'gcc' with the same prefix is available as well.

Without a check detect_compiler_runtime() would try to execute an
    unavailable binary and print something like this:
    .../xcompile: line 218: arm-linux-gnueabi-gcc: command not found
