Why not 'cheat'? Automake knows when CXX is needed (it will complain if
AC_PROG_CXX is not present), so let automake call the libtool tag
configuration after configure time, for the needed tags. That would also
as a by-product split out the various tags making the scripts that are
executed smaller.

Agreed.
