#8-) Never call a check program "test" - This should be a programming

Implement an AM_CHECK_MAKE (or similar) to check if the make in use is
able to handle VPATHS as part of automake.
If all else fail, blacklist Solaris make for use with automake.

As I read it, it's what effectively what it says.

As a consequence of this, it would only be logic to reflect this
behavioral change into automake, which would render many things in
automake much easier.

The next logic step would be to make bash mandatory for autoconf ...

Do you now sense the irrationality of your approach?

Wrong. This is not autoconf's task, therefore you are in error to let
autoconf take care of it.

If automake doesn't work with VPATH's but gmake, automake should
implement this feature. 

Or, if this problem is limited to a subset of applications, these
applications should check for gmake.

So you agree, that making bash mandatory for autoconf is tremendous
