Thanks. That approach should work for a recursive setup if each directory with Makefile.am also has the MAKEFLAGS-altering GNUmakefile. From my perspecitve, while it would be nicer if Automake handled it for me, this solution appeals. I realize converting to nonrecursive make would yield correctness and performance wins, but so far I have been put off by the loss of ability to build only a subtree.
It is quite possible to build a subtree of a non-recursive project but you do need to know how to specify the fully-qualified path to the target which should be built. If there are just a few common targets, these can be added as shortcut targets in the Makefile.
