This is what sprang to mind as I read your description of the problem. 
Building static libraries would also work, but is going to significantly 
increase the amount of storage required during 'make check'.  On the other 
hand, it may result in more reliable tests, since you don't have to depend 
on being able to force runtime linker to pick the library under test 
instead of some already-installed one.
