This depends mostly on your intentions and for sure on the packages 
options. If you have the choice, to statically compile the libs into the 
packages, then you don't need it in your minimal-root. This is an 
option, when the package has a static use flag. But if it has no option 
for static compiling, then the package needs to have the lib available 
because it uses the lib at runtime. For example, busybox supports static 
compiling and is able to run without any library, if you give it the 
static use flag. But be aware of other packages. Most of them don't 
support it.
