Right - it is kind of unfortunate that we use an empty string to mean 
"all", while also using an algebra whose identity element is "none".

I would propose we introduce an explicit qualifier ".ALL" for this.

E.g.

.STATIC: .ALL:
     ...

.STATIC: .ALL: foo.txt
     TXT = $(cat foo.txt)

We can still allow omitting .ALL in the first case (no dependencies), 
but not in the second one.
