No, ideal for changing the default a whole subtree is to put the change
in Makefile.inc at the top of the tree and inherit this recursively.
The MAKEFLAGS hack fails for normal builds (when `make' is run in a leaf
directory) because it doesn't affect the current invocation of make.

Only the setting of LIBDIR in bsd.own.mk is wrong if a Makefile[.inc]
changes OBJFORMAT.  This is fairly harmless except for installng libraries.
