So, if I understand it correctly from gprof(1), profiled libraries are
for measuring how much CPU time is spent in each suboutine?  And, as a
regular user (not a developer or benchmarker), I don't need this and can
use -DNOPROFILE for not building profiled libraries?  

I also understand these libraries are seperate from my "regular"
libraries?  So, is there a drawback (other than increased compile time
for a make world) in building them?  Or does it not matter?
