    Use a non-empty test program to test ability to link.

    On bare-metal targets, I/O support is typically provided by a BSP and
    requires a linker script and/or hosting library to be specified on the
    linker command line.  Linking an empty program with the default linker
    script may succeed, however, which confuses libstdc++ configuration
    when programs that probe for the presence of various I/O features fail
    with link errors.
