[PATCH] testsuite: endianness in gnu_vector.exp

[jose.marchesi@oracle.com (Jose E. Marchesi)]

Hi.

Small patch making gnu_vector.exp to work properly in big-endian
machines.

Tested in sparc64-*-linux-gnu.

2013-10-07  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* gdb.base/gnu_vector.exp: Care about endianness when casting
	scalars to vectors.
