* sysdeps/alpha/dl-machine.h (RTLD_START): Fix top-of-stack backtrace. * sysdeps/unix/sysv/linux/alpha/clone.S: Likewise. * sysdeps/alpha/elf/start.S: Likewise. Remove pointless allocation. * sysdeps/unix/sysv/linux/alpha/rt_sigaction.S: Use standard ldgp entry sequence and explicit relocs. Add unwind info for sigreturn and rt_sigreturn. * configure.in (libc_cv_asm_cfi_directives): Test .cfi_remember_state. * configure: Regenerate.
