Makefile: Add cleanall-symlink target

This target looks for symbolic links in the coreboot directory,
excluding the 3rdparty and crossgcc directories, which both typically
have numerous symbolic links, and deletes anything that is found.

All possible links are verified as symbolic links before being removed.

Any removed links show where they were linked from in case they need to
be restored.
