Accommodate debug-kernel stack frame size 

The blk_queue_discard() and blk_queue_sector_erase() functions
slightly exceed the allowed 4096 maximum stack frame size when
building with the RedHat debug kernel which causes their
configure checks to fail.

Add an exception for these two tests so the interfaces are
correctly detected.
