Such flags are a big problem to get right.

What if
  check_PROGRAMS = foo
  bin_PROGRAMS = foo

happens?  Which rule should win?  I don't think we even forbid this kind
of setup, just like we don't forbid sources being listed for more than
one program or library.

Sticking special flags or LDADDs to specific targets OTOH is always
well-defined.
