  Actually, I think this should be

$(2)_SUBDIR ?= $$($(3)_SUBDIR))

  There definitely shouldn't be an assignment to $(3)_SUBDIR here,
and also the whole ifdef construct is unnecessary.

  This looks like a missed refactoring opportunity:

_SRCDIR is still assigned to in pkg-cmake.mk

I don't see why anybody would want to override _BUILDDIR, so the ?= is
redundant.  And since it's always equal to _SRCDIR, why not just use
_SRCDIR?
