Sure, updated patch below.

-------------------

This patch updates two attach tests to use utility procs
for checking if the attach test should run and for 
launching the program to be attached, as follows:

1) Use can_spawn_for_attach instead of is_remote target
2) Use spawn_wait_for_attach instead of exec/sleep

Tested (1) with i686-mingw32 host and i686-pc-linux-gnu build/target
and both with x86_64 Ubuntu.

2015-01-14  Don Breazeal  <donb@codesourcery.com>

	* gdb.base/attach-pie-noexec.exp: Use can_spawn_for_attach
	instead of checking whether the target board is remote and
	use spawn_wait_for_attach instead of exec/sleep.
	* gdb.base/attach-twice.exp: Likewise.
