[ale] GNU Makefile auto target

[alan at alanlee.org]

The first target is the default target only if you do not specify any. 
Not sure that's what the OP was asking. 

If you want something to always run before (eg. from the original email)
'all', make a .PHONY target (means no build products) 'foo' and make it
a dependency of all the rest of your targets.  I don't believe there is
a way to say target 'foo' is a dependency of everything else without
expressly adding it to each of their dependency lines.  Otherwise you
could have 'bar' with the same global directive and it would not be able
to reconcile the execution order priority between the two.
