I have a large build system that includes several third party autoconf libraries. To get everything on place I call "make install" on all the subprojects. That copies (and touches) the include files even if there has been no changes. That causes the downstream build to rebuild a lot of things.
I was using make -q to find out of I needed to do the sub-make before running it. I've worked around the problem using find -newer on the build tree.
