Author: dim

New Revision: 242552
URL: http://svn.freebsd.org/changeset/base/242552

Log:
  MFC r236258:
  
    For clang, similar to r236137, enable gnu hash generation for dynamic
    ELF binaries on x86.
  
  MFC r238863:
  
    Similar to r238472, let clang pass --enable-new-dtags to the linker
    invocation by default.  Also make sure --hash-style=both is passed for
    the same arches as gcc, e.g. arm, sparc and x86.
