Doesn't make only executes this target if the file/symlink is not current?
Unfortunately not.
Maybe '$(LN_S) -f' is better for the case that it thinks its not 'current'?
Didn't like the force here as the link is always good if just kept.
What is your reason for this? My reason is simplicity over complexity.
If you insists on this, maybe write it like this:
test -e bg_printenv || $(LN_S) bg_setenv bg_printenv
