Actually, as I look at it, this second one doesn't seem to make any sense to me.
_INSTALL as a variable doesn't seem to get used anywhere that I can see,
certainly not in the capacity of copying shared libraries into the build/lib
area so that the example apps can get linked with them.  So I'm not sure this
makes sense.
