The symlinks are needed to allow shared libraries to be 
easily upgraded in-place.

The uClibc 'make install' command (and all the variants on that
theme such as 'make install_runtime') do in fact install such a
symlink....  Perhaps you just copied things rather than using
i.e. 'make install_runtime'?
