Comment (by leif):
Or, how does `make INST="${SAGE_SPKG_INST:-installed}"` behave? (I think
this would be better.)

I meant just in the `Makefile`. (`$SAGE_SPKG_INST` could still be
absolute.)

`$SAGE_SPKG_INST` from some other directory (which can and does happen)
See above.

I was just kidding.

$SAGE_SPKG_INST`.
Well, just change `INST = installed` to something else (`INST =
this_is_always_the_relative_path_to_a_symlink`), and let it point to
either `installed` or `$SAGE_SPKG_INST` (where the latter is absolute).
Not sure about performance issues.
