nit: I'm not sure there's any merit in the $(@:_install=) construct,
when it's only really needed when there are multiple targets in the same
rule. For ynl_install, $(call descend,net/ynl,install) would be just
fine. It's funny that the existing convention in this Makefile is to
mostly use substitution for the _install rules, but literals for the
_clean rules.

Either way:
