Not really.  The problem is that makefile syntax is highly
context-dependent: for example, wildly different syntactical rules hold
inside a rule's command script than do during variable assignment.

For this reason most instances of make I'm aware of have hand-rolled
parsers rather than utilizing yacc, or even lex.
