* unix/ldAix: remove ancient (pre-4.2) AIX support

        * unix/configure: regen with ac-2.59
        * unix/configure.in, unix/tclConfig.sh.in, unix/Makefile.in:
        * unix/tcl.m4 (AIX): remove the need for ldAIX, replace with
        -bexpall/-brtl.  Remove TCL_EXP_FILE (export file) and other
        baggage that went with it.  Remove pre-4 AIX build support.
