    tree-wide: Do not use package librt and libpthread
    
    The libraries libpthread, libdl, libutil, libanl have been integrated
    into the libc library in version 2.34. it is not needed to explicitly
    link them any more.
    
    Most of the functions have been moved from the librt.so into libc.so
    some time ago already.
