    Some ".." need to be changed to $(MPTOP), and in some places "ports/" needs
    to be inserted to get to the "ports/unix/" subdir.

    # _FORTIFY_SOURCE is a feature in gcc/glibc which is intended to provide extra
    # security for detecting buffer overflows. Some distros (Ubuntu at the very least)
    # have it enabled by default.
    #
    # gcc already optimizes some printf calls to call puts and/or putchar. When
    # _FORTIFY_SOURCE is enabled and compiling with -O1 or greater, then some
    # printf calls will also be optimized to call __printf_chk (in glibc). Any
    # printfs which get redirected to __printf_chk are then no longer synchronized
    # with printfs that go through mp_printf.
    #
    # In MicroPython, we don't want to use the runtime library's printf but rather
    # go through mp_printf, so that stdout is properly tied into streams, etc.
    # This means that we either need to turn off _FORTIFY_SOURCE or provide our
    # own implementation of __printf_chk. We've chosen to turn off _FORTIFY_SOURCE.
    # It should also be noted that the use of printf in MicroPython is typically
    # quite limited anyways (primarily for debug and some error reporting, etc
    # in the unix version).
    #
    # Information about _FORTIFY_SOURCE seems to be rather scarce. The best I could
    # find was this: https://securityblog.redhat.com/2014/03/26/fortify-and-you/

    # https://gcc.gnu.org/ml/gcc-patches/2004-09/msg02055.html .
