    Drop the fpic multilib for powerpc*-vxworks*
    
    The addition of fPIC for shared libraries is performed
    independently from multilibs and the fpic multilibs have
    no other particular purpose. They incur extra build time,
    complexify the install tree and are a bit tricky because
    -fpic is not supported for kernel mode.
