The SDK Makefile still trys to copy the docs folder which was removed
with 882f4d2d63. This causes an SDK build
error.
All other removals are just cleanup.

Apparently symlink-tree has not been used in quite some time as it
fails to symlink the always required config dir
Also, if we pulled from git but .git is missing we get
many error messages on the symlinked tree without this
patch (which symlinks .git, if present)
