    gnu: datefudge: Only use glibc-2.31 workaround on supported platforms.
    
    The powerPC port is using glibc-2.30.
    
    * gnu/packages/time.scm (datefudge)[source]: Remove patch.
    [arguments]: When not on powerpc-linux, add phase to adapt the code for
    glibc-2.31.
    * gnu/packages/patches/datefudge-gettimeofday.patch: Remove file.
    * gnu/local.mk (dist_patch_DATA): Remove it.
