[PATCH 1/2] Add tst-jmp_buf.c and jmp_buf-macros.h

From: "H.J. Lu" <hongjiu dot lu at intel dot com>
To: GNU C Library <libc-alpha at sourceware dot org>
Date: Tue, 7 Nov 2017 14:38:21 -0800
Subject: [PATCH 1/2] Add tst-jmp_buf.c and jmp_buf-macros.h
Authentication-results: sourceware.org; auth=none
Reply-to: "H.J. Lu" <hjl dot tools at gmail dot com>
Verify that sizes, alignments and field offsets of jmp_buf as well as
sigjmp_buf are unchanged regardless how struct __jmp_buf_tag is defined.
Since jmp_buf is target specific, jmp_buf-macros.h is added for each
target.  The new target must provides its own jmp_buf-macros.h.

Tested with build-many-glibcs.py.

OK for master?

H.J.
