[PATCH] Fix tst-sscanf and tst-swscanf on 64-bit

[David Miller]

In the glibc-2.19 port status entry for sparc 64-bit I indicated
that these two tests get a bus error, and I just figured out why.

The dummy variable passed to sscanf() in the int_tests[] run needs
to be at least as large as a pointer.

MIPS 64-bit was probably failing in an identical way.  It will fail on
any 64-bit platform where unaligned accesses generate an exception.

Ok to commit?

	* stdio-common/tst-sscanf.c (main): Use 'long' for 'dummy' when
	processing int_tests.
