    bsd.lib.mk: add conditions for building _pie.a archives
    
    As with other .a targets, build _pie.a archives only if LIB is set.
    
    At present we build _pie.a only for INTERNALLIBs, and none of them
    include bsd.lib.mk without setting LIB.  However, we might want to build
    _pie.a for non-INTERNALLIBs in the future.
