Correct, part of a lot of recompilation might come from the check 
symbols stuff that force every lib to be recompiled, I suspect that we 
can add an option to not enable it (enabled by default in 
./configure.developer) and with the use of --targets it should help.

As said on irc, if you are working on a lib like talloc or ldb, doing 
waf --targets=<lib>.objlist will just compile the .o for this object
