--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
-mabi=ibmlongdouble -mno-gnu-attribute is coming from libgfortran's configure:

      AC_PREPROC_IFELSE(
        [AC_LANG_PROGRAM([[#if __SIZEOF_LONG_DOUBLE__ != 16
                           #error long double is double
                           #endif]],
                         [[(void) 0;]])],
        [AM_FCFLAGS="$AM_FCFLAGS -mabi=ibmlongdouble -mno-gnu-attribute";
         AM_CFLAGS="$AM_CFLAGS -mabi=ibmlongdouble -mno-gnu-attribute";
         CFLAGS="$CFLAGS -mabi=ibmlongdouble -mno-gnu-attribute";
         have_real_17=yes])
