gentoo bug 259184 - spurious testsuite failure

[Eric Blake]

http://bugs.gentoo.org/show_bug.cgi?id=259184

reports a failure where the testsuite expects ENOENT, but hardening root means 
it gets EACCES instead.  Since the access is denied either way, and m4 detects 
the failure at opening the impossible path, the bug is in the testsuite for not 
being tolerant to the spelling in the error message.  Fixing as follows:

Subject: [PATCH] Avoid test failure due to different errno.

* doc/m4.texinfo (Using frozen files): Ignore stdout, since
hardened systems can prevent attempts to read /.
* THANKS: Update.
Reported by Ronny Peine, in Gentoo bug 259184.

        Avoid tests that make no sense, because m4 is single-threaded.
        * m4/gnulib-cache.m4: Avoid lock-tests and tls-tests.
