Makefile: Add targets to add and remove symlinks

When "make symlink" is run, it looks for symlink.txt files recursively
under site-local directory, and make symbolic links accordingly.

"make clean-symlink" removes the symbolic links made.

One application is for development of support for new processors and/or
new mainboards, where new directories are added, along with some common
code changes.
