    Centralize GNU utility checks in autoconf · 0d8ba680

    Tests for program presence, such as those formerly embedded in the
    top-level Makefile for gawk and gsed, are better suited for autoconf.
    
    Note that it is not sufficient to merely export AWK and SED environment
    variables, as packages may still directly invoke awk(1) and sed(1) with
    non-standard features independent of the autotools framework.
    Wrapper scripts therefore remain necessary, although these are now
    generated by the configure script to avoid hard-coded paths.
    
    Do not assume the existence of /bin/bash on all systems.
