It would be very hard to implement, I'm afraid.
The problem is that Automake aims to create portable makefiles, so
the language is quite limited.

Most of the problems are handled by AM_CONDITIONALs.
You can say:

if FOO
  myprog_LDADD += liba.a
endif

and the  myprog_DEPENDENCIES  are then computed correctly.

The situations when this is not enough are probably rare enough that
it's not worth it to create a complicated solution.

Have a nice day,
