[bug #30381] Don't avoid implicit rule recursion quite so soon.

[Reinier Post]

Follow-up Comment #11, bug #30381 (project make):

Strike my last comment: invoking a rule multiple times in a chain appears to
work just fine.

To prove this, here is a patch against the make 3.82 source that adds a -M
option, which allows this; a test script is included, but string translations
and documentation updates are missing.

The idea is really simple: it replaces rule->in_use with rule->nr_reuses and
compare that number against the value of -M.  Note that -M without an argument
means 'infinite' (same as for -j), so it allows rule chaining to go into an
infinite loop.

I will use this as a workaround for myself.  I didn't use the idea discussed
below (to allow recursion only when the dependency is shorter than the target)
only because it was slightly harder to implement.
