	* gdb.base/huge.exp: New test.  Print a very large target data object.
	(skip_huge_test): New test variable.  Define if you want to skip this
	test.  The test reads an 8 megabyte data object from the target, so it
	might be very time consuming on remote targets with a slow connection.
	* gdb.base/huge.c: New file.  Test case for above.
