a very sophisticated trick that is, a simple one might be to
add the rebuild rule on every instance where a library is
linked that exists in the same configured tree:

name_LDADD = ../other/libthing.la

../other/libthing.la : ../other/*.c ../other/*.h
        cd ../other && $(MAKE) `basename address@hidden

that works with every automake version IYAM, if you can
live with it, you could even leave out the righthand deps
which will `make` to make a short step over into the other
build dir quickly returning without doing anything there.
