    Add extra configuration and sanity checks for groff and ps2pdf
    
    1) Add AC_ARG_VAR for GROFF and PS2PDF to inform users of these
       environment variables.
    2) Check that groff -ms works
    
    Some distributions ship the ms macros as a separate package which may
    not be installed together with groff, so we need to make sure that groff
    works and the required macros are actually installed before attempting
    to build the specs.
