* sysdeps/mips/dl-machine.h (_RTLD_PROLOGUE): Reformat. Declare

as function.
        (_RTLD_EPILOGUE): Reformat.  Declare size of entry function.
        (ELF_MACHINE_BEFORE_RTLD_RELOC): Relocate the dynamic linker itself so
        it will even work when not loaded to the standard address.
        (RTLD_START): Reformat.  Call _dl_start in a way that is safe even
        before the dynamic linker itself is relocated.
