        * elf.c: Eliminate references to __sparcv9 macro; replace with
        autoconf variables HAVE_PSINFO32_T etc.
        * configure.in: Auto-configure HAVE_PSINFO_32_T, HAVE_PRPSINFO32_T,
        HAVE_PSTATUS32_T, HAVE_PRSTATUS32_T, HAVE_PRSTATUS32_T_PR_WHO.
        * config.in: Ditto.
        * acinclude.m4 (BFD_HAVE_SYS_PROCFS_TYPE) define _SYSCALL32 so it can
        detect the above typedefs.  (BFD_HAVE_SYS_PROCFS_TYPE_MEMBER): Ditto.
        * aclocal.m4: Ditto.
        * configure: Regenerate.
