Richard Henderson 549046b742 Update.
1998-06-27  David S. Miller  <davem@pierdol.cobaltmicro.com>

        * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_matches_host):
        Cleanup weak_extern usage for _dl_hwcap and _dl_hwcap_mask.
        (elf_machine_fixup_plt): Likewise.
        * sysdeps/unix/sysv/linux/sparc/sparc32/getpagesize.c: When
	_dl_pagesize not set, use system call to always get correct answer.
        * sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list
        (__syscall_getpagesize): Add
