    libphobos: Add power*-*-freebsd* as supported target
    
    This has been tested on powerpc64-freebsd13 and powerpc64le-freebsd13,
    and used to build dub, along with some D tools from ports.
    
    libphobos/ChangeLog:
    
            * configure.tgt: Add power*-*-freebsd* as a supported target.
            * libdruntime/core/sys/freebsd/config.d: Define
              __FreeBSD_version for FreeBSD_13 targets.
    
    (cherry picked from commit 0c3fc06c300f5b71f299812c7fcac82b0236e5ac)
