    [build]: Preserve byacc/bison output artifacts.
    
    * src/preproc/eqn/eqn.am (MAINTAINERCLEANFILES):
    * src/preproc/pic/pic.am (MAINTAINERCLEANFILES):
    * src/preproc/refer/refer.am (MAINTAINERCLEANFILES): Preserve
      byacc/bison output artifacts unless "maintainer-clean"ing.  Per the
      GNU Automake manual, "The intermediate files generated by yacc (or
      lex) will be included in any distribution that is made.  That way the
      user doesn’t need to have yacc or lex."
