commit 87119fa3e7ac1ba4e1b41716380dfc5bde62cb8c

    test: don't hang waiting for Solaris lex/yacc to read from stdin.
    
    From https://bugs.gnu.org/68165.
    
    * t/get-sysconf.sh: Don't let $LEX or $YACC read from stdin when
    trying --version and --help. Only lex --version hangs, but may
    as well avoid it in general.
