And I've just found another problem related to AC_CANONICAL_BUILD placed
to late (or ltmain= substitution too early). For this one cross compiler
is not needed. Just add one more line at the end of the above configure.ac:

echo "LIBTOOL_DEPS: $LIBTOOL_DEPS"

then regenerate configure.

`./configure` output ends with:
LIBTOOL_DEPS: /ltmain.sh

`./configure --with-canonical` output ends with:
LIBTOOL_DEPS: ./ltmain.sh

Note the missing "." in the first case. It's because of empty ac_aux_dir
(used for ltmain substitution in configure) which is set by one of
AC_CONFIG_AUX_DIR* macros, with default one called from
AC_CANONICAL_BUILD.
