* Bug Fixes
    - Fixed RCCL build in ROCm 6 due to installation path changes.

      support.
        * Thanks to Raghu Raja @Amazon for report.
    - Resolved a bug in the maximum memory limit check, which previously
      considered only the memory allocated by a single buffer. This check and
      command line option 'M' no longer exists.
        * Thanks to Van Man Nguyen @Eviden for report and patch.
    - Fixed bug while printing validation results in some collective benchmarks.
    - Updated reduction benchmarks to use MPI_SIGNED_CHAR 
       instead of MPI_CHAR.
        * Thanks to Rémi Dehenne @CEA for report and patch.
    - Fixed a bug in Reduce, Reduce-Scatter benchmarks that caused validation
      to fail when running with ROCM support.
        * Thanks to Anton Daumen @Eviden for report and patch.
        * Thanks to Edgar Gabriel @AMD and Mustafa Abduljabbar @AMD for report.
    - Fixed RCCL check in configure script.
        * Thanks to Anton Daumen @Eviden for report.
