[PATCH] autotools: Correct dependency search logic error

[PATCH] autotools: Correct dependency search logic error

[Richard Purdie]

We go to the effort of finding the value of start, we should then use it
rather than relying on the value of dep being preserved from the previous
loop. Took me far too long to notice this issue when changing the code.

Also drop an unused variable.
