--- Comment #23 from Iain Sandoe <iains at gcc dot gnu.org> ---
something like this 

dnl Check if the current compiler supports -mno-dynamic-no-pic.
AC_DEFUN([GCC_CHECK_FLAG_NO_DYNAMIC_NO_PIC], [
  AC_CACHE_CHECK([whether the current compiler supports -mno-dynamic-no-pic],
         ac_cv_have_mno_dynamic_no_pic, [
  mno_dynamic_no_pic_saved_CFLAGS="$CFLAGS"
  CFLAGS="$CFLAGS -mno-dynamic-no-pic"
  AC_TRY_COMPILE([void foo(void) { }],
         [], ac_cv_have_mno_dynamic_no_pic=yes,
         ac_cv_have_mno_dynamic_no_pic=no)
  CFLAGS="$mno_dynamic_no_pic_saved_CFLAGS"])
  if test x"$ac_cv_have_mno_dynamic_no_pic" = xyes; then
    MDYNAMIC_NO_PIC=-mdynamic-no-pic
    MNO_DYNAMIC_NO_PIC=-mno-dynamic-no-pic
  else
    MDYNAMIC_NO_PIC=
    MNO_DYNAMIC_NO_PIC=
  fi])

but .. the results need to be available to the mh-darwin
