actually, this is a good reason for the dependency to not exist

buildroot needs to hook in and install just the header files (before the first 
cross gcc is built) ... if buildroot is doing something wrong such that the 
libs are not being built before attempting to install, then buildroot should 
be fixed

sure, if you feel like tackling that, g'luck ... i deemed it not worth the 
effort ... especially the overhead of watching make recurse through the whole 
directory tree is annoying

not all libs do it, just some (like libc for sure)
