Revert "add configure check for date_time lib"

This commit breaks MinGW builds; the m4 macros probably need some
improvements there.

This reverts commit 5ed17233908c7f87b08b0964b55e4504d964ed71.

-# SYNOPSIS
-#
-#   AX_BOOST_DATE_TIME
-#
-# DESCRIPTION
-#
-#   Test for Date_Time library from the Boost C++ libraries. The macro
-#   requires a preceding call to AX_BOOST_BASE. Further documentation is
-#   available at <http://randspringer.de/boost/index.html>.
-#
-#   This macro calls:
-#
-#     AC_SUBST(BOOST_DATE_TIME_LIB)
-#
-#   And sets:
-#
-#     HAVE_BOOST_DATE_TIME
