I also wondered that the point of this was.
The SHELL make/env variable lets you set the shell make should use for
all its commands.  This can to be a full path.

I think the tables are used to sort out how make should drive the
various shells (eg when trying to use a single shell to execute a
group of commands).
As such it should be using the 'basename' of $SHELL to determine
which table to use.
