Thanks for finally clearing this up.

But the cross-compilation behaviour is changed: it now sets
  ac_cv_type_long_long_int=cross-compiling
and then also
  ac_cv_type_long_long=cross-compiling

which needs consequential changes at least in these places:

intmax_t.m4:22:    test $ac_cv_type_long_long = yes \
intmax_t.m4:55:    test $ac_cv_type_long_long = yes \
longlong.m4:68:  if test $ac_cv_type_long_long = yes; then
stdint.m4:16:  if test $ac_cv_type_long_long_int = yes; then
strtoll.m4:12:  if test "$ac_cv_type_long_long_int" = yes; then

Also, this will cause trouble in packages that use existing gnulib
macros (such as gettext of any version <= 0.16) if they reconfigure it
with a newer autoconf.

Since the comment already says that when cross-compiling we can assume
that the bug is not present, I'd propose to set ac_cv_type_long_long_int
to the value it had before:

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Set ac_cv_type_long_long_int
        to 'yes' instead of 'cross-compiling'.
