Because the test has no comments, it was not clear to me if it was
specifically testing large format strings or just large output.  If only
the latter, then using a "%s" format would be the better fix.  But this
fixes the build without changing what the test tests.

With this, I have no more build errors in 'make check' for x86_64-linux-gnu
using the Ubuntu 14.04 gcc-4.8.2 that breaks command-line -Wno-format.


	* misc/tst-error1.c (do_test): Ignore -Wformat-security for
	generated error format strings.
