ulib: Add an option to build U-Boot as a library

Browse Source 
It is sometimes useful to create a different main program for U-Boot,
or even to use some parts of U-Boot in an entirely different project.
Add a new option to allow building a .so from parts of U-Boot. For now
this does nothing.

Enable it by default for sandbox, excluding the tools-only build, where
it has no meaning.
