	* sysdeps/s390/bits/link.h: New file.
	* sysdeps/s390/s390-32/dl-trampoline.S: New file.
	* sysdeps/s390/s390-64/dl-trampoline.S: New file.
	* sysdeps/s390/s390-32/dl-machine.h: Move PLT trampolines to
	dl-trampoline.S. Use RESOLVE_MAP instead of RESOLVE to protect
	relocation code.
	(elf_machine_runtime_setup): Test for dl_profile non-null.
	(elf_machine_rela): Remove code using RESOLVE.
	(ARCH_LA_PLTENTER, ARCH_LA_PLTEXIT): New.
	* sysdeps/s390/s390-64/dl-machine.h: Likewise.
	* sysdeps/generic/ldsodefs.h (La_s390_32_regs, La_s390_32_retval,
	La_s390_64_regs, La_s390_64_retval): New.
	* elf/tst-auditmod1.c: Add s390 entries.
