libtool script built by your project configure.  Now we set the
default tags depending on whether AC_PROG_CXX et. al. are actually
called from configure.ac.

* libtool.m4 (_LT_AC_TAGCONFIG): Don't default the tagnames when
no --with-tags argument is given.
(_LT_AC_SHELL_INIT): Factored out from the AC_DIVERT_PUSH code
in...
(_LT_AC_PROG_ECHO_BACKSLASH): ...which now calls the macro
instead.
(AC_LIBTOOL_CXX): Use _LT_AC_SHELL_INIT to add CXX to the
initialisation sequence for tagnames.
(AC_LIBTOOL_GCJ): Similarly for GCJ tag.
(AC_LIBTOOL_RC): Likewise for RC tag.
