build system: Split linking into multiple steps

After collecting dependencies for ramstage, add an intermediate step
    in which object files are linked per directory. The results are then
    linked into the final binary.

This reduces the maximum command line length and might also help with
    future use of LTO linking.

Also adapt the lint test for build dir handling, since printall
    doesn't provide individual object files for ramstage anymore.
