Update.
2001-07-13  H.J. Lu  <hjl@gnu.org>

	* sysdeps/mips/dl-machine.h (MAP_BASE_ADDR): Removed.
	(elf_machine_got_rel): Defined only if RTLD_BOOTSTRAP is not defined.
	(RESOLVE_GOTSYM): Rewrite to use RESOLVE.

	* sysdeps/mips/rtld-ldscript.in: Removed.
	* sysdeps/mips/rtld-parms: Likewise.
	* sysdeps/mips/mips64/rtld-parms: Likewise.
	* sysdeps/mips/mipsel/rtld-parms: Likewise.
