INSTALLPATH defaults to “lua somefile.lua”, and it is applied to the
name of the module (“bit”).  If I just changed INSTALLPATH to a literal
path, the “install” target would try to execute it with “bit” as an
argument.

This is why I’m using “printf”, which when given a string literal
ignores any other arguments.  The result is just the install path.  I
chose this method over patching the Makefile.
