Add to the "Depends on" list.

    libgfortran: Use __builtin_issignaling in libgfortran [PR105105]

    The following patch makes use of the new __builtin_issignaling,
    so it no longer needs the fallback implementation and can use
    the builtin even where glibc provides the macro.

            * ieee/ieee_helper.c: Don't include issignaling_fallback.h.
            (CLASSMACRO): Use __builtin_issignaling instead of issignaling.
            * ieee/issignaling_fallback.h: Removed.
