message. Add include of <stddef.h>.
(INIT_NEW_WAY): New macro.
(INIT_OLD_WAY): Likewise.
(_init): Add unwind directives. Invoke
__pthread_initialize_minimal() via INIT_NEW_WAY or INIT_OLD_WAY,
respectively.
(_init_EPILOG_BEGINS): Add unwind-directives. Drop unused .regstk
directive.
(_fini): Add unwind directives. Drop unnecessary .align 16
directive (bundles are always 16-byte aligned).
(_fini_EPILOG_BEGINS): Add unwind-directives.
