[PATCH] testsuite/gdb.base: Make skip test not rely on undefined behaviour.

[Will Newton <will.newton@linaro.org>]

The skip test currently relies on the order of evaluation of
arguments which is not defined. Use an arithmetic expression
where order is defined instead.

gdb/testsuite/ChangeLog:

2013-06-07  Will Newton  <will.newton@linaro.org>

	* gdb.base/skip.c: Add results of foo() and bar() before
	passing to baz().
	* gdb.base/skip.c: baz() now takes one argument instead of
	two.
