    linker: fix OpenBSD build failure, EM_PPC64 is not defined there
    
    Adam Steen reported build failure on OpenBSD:
      rts/linker/Elf.c:402:0: error:
        error: 'EM_PPC64' undeclared (first use in this function)
          case EM_PPC64: IF_DEBUG(linker,debugBelch( "powerpc64" ));
    
    OpenBSD-6.0 does not define EM_PPC64:
      /usr/include/sys/exec_elf.h:#define EM_PPC 20 /* PowerPC */
    
    Reported-by: Adam Steen <adam at adamsteen.com.au>

    (cherry picked from commit 6c73504ac5f4e951062d5e868fa2b69b028b6e79)
