    Fix PR sim/13418: building with --enable-targets=all fails

    Multitarget builds currently fail when:

     (1) simulator support is enabled (the main --target supports target sim)
     (2) powerpc is included in the --enable-targets list
     (3) powerpc is not the main/default target (--target)

    This is because the powerpc sim provides a non-standard API function
    sim_spr_register_name which gdb/rs6000-tdep.c utilizes.  Since the sim
    does not yet support multitarget, only the sim (if one exists) for the
    main target is built.  When that target isn't powerpc, this function
    is not available leading to linking errors:

        rs6000-tdep.c:(.text+0x1e34d): undefined reference to
        `sim_spr_register_name'

    Fix this by only using that API if the sim linked in is the powerpc
    sim.
