SERVER-12751 remove BSONBuilderBase
SERVER-9570 SERVER-9572 Default install prefix to subdirectory of selectable build dir

SERVER-14343 Build fast and loose by default
SERVER-11290 Don't actually build static libraries

We don't currently use the static libraries, they are just nodes in our
dependency graph. Since they are unused, building them wastes time and disk
IO.

We still need to generate the files to appease scons. They are filled with a
UUID on the assumption that if scons thinks that a library needs to be rebuilt
then anything that depends on the library should also be rebuilt.
