[hackers] [9base] install lib9.a || sin

commit 4fe8994317557febe21758a92fe26edbce6d517d

    install lib9.a
    
    This patch installs lib9.a in ${DESTDIR}${PREFIX}/lib/ so it can be
    linked against with -l9 (given the correct -L). I found that necessary
    to compile y.tab.c generated by 9base's yacc due to sprint().
    
    Patch contributed by Evan Gates.
