running L from outside the path where it was built leads to issues

[HalosGhost]

Even when $PREFIX has been set correctly, if L is moved outside its build-tree, it does not function properly.

Namely, it seems to fail to find the L-specific libl.tcl library needed to operate properly.

Running strings, we get the following

$ strings L | grep tcl8.6
../.././L/lib/tcl8.6
/lib/tcl8.6

That is, L looks for libl.tcl in only two places: where it would be located inside it's build tree and the system copy.

Talking in the IRC channel, georgn suggested the following:

10:19:07      @georgn | in our top level Makefile, we define INSTALL_ROOT -- I'm guessing that's the culprit
