Description of Problem:

The %GNUconfigure macro is broken in several aspects:
- it does not set CXXFLAGS
- it sets LDFLAGS to an empty string; with recent autotools
(autoconf-2.52-3, automake-1.5-1) it fails to detect the C++ compiler,
because it tries to execute "g++ '' conftest.cc" in a autoconf-test. There
'' is the value of $LDFLAGS and g++ won't find this file.
- adding additional flags to ./configure is not intuitive (you have to
execute %{GNUconfigure -- --extra-flags=...}). A solution could be a
definition of %GNUconfigure as a sh-function and calling this at the end:

| % define GNUconfigure(MCs:)
|   function __rpm_gnuconfigure {
|      ... body ...
|      ./configure ... "$@"
|      ...
|   }; __rpm_gnuconfigure

- the filename "configure.in" (used in some tests) is deprecated in recent
autotools; configure.ac is recommended now

- the whole libtoolize/autoheader/aclocal/autoconf stuff can be replaced by
a simple "autoreconf -i"
