make: fix typo in inference rule handling

A typo in the previous commit caused dyndep() to process inference
rules incorrectly.  This didn't affect the results of the test suite
when extensions were allowed but it caused the test 'Inference rule
with explicit rule for prerequisite' to fail in POSIX mode.
