The opinions on this matter are certainly not unanimous.
On the one hand, there is the issue you mention that re-make thinks the
target is up-to-date, although it isn't (it exists but is result of a
failed link, and does not have execute permission).  On the other hand,
a link may take a long time, and the output file from a failed link may
give useful clues as to the problem a programmer may encounter.

Regardless of possible value for debugging, leaving a broken target behind which influences the next build attempt is clearly wrong behavior. A goal of autotools should be to obtain consistent behavior in an inconsistent world. Leaving stray files behind represents inconsistent behavior which should be rectified.
