It's probing for top-level targets. So if there is a way to query ninja
for that it's easy enough to write a probe to collect them. The make
-nqp stuff is a little janky but basically greps for .PHONY patterns and
assumes a .PHONY target is a top level target. The help parsing is pure
regexery:

  (defvar counsel-compile-phony-pattern "^\\.PHONY:[\t ]+\\(.+\\)$"
    "Regexp for extracting phony targets from Makefiles.")

  (defvar counsel-compile-help-pattern
    "\\(?:^\\(\\*\\)?[[:space:]]+\\([^[:space:]]+\\)[[:space:]]+-\\)"
    "Regexp for extracting help targets from a make help call.")

I guess I'll have to see what:

  ninja -t targets all

lists.
