[RFA/testsuite] Handle MIPS in step-test.exp

[Daniel Jacobowitz <drow@mvista.com>]

The MIPS PIC calling conventions have a $gp register which needs to be
reloaded after function calls, so they need the same treatment IA-64 and PA
do in step-test.  I also needed to finish stepping past one call before
looking for the next or the test showed a bogus failure.

Is this OK?

	* gdb.base/step-test.exp: Allow MIPS to return to the line of a
	function call.
