Maybe I am missing something, by how about clearly stating
that you can have several lvalues and rvalues?  The following
grammar has no conflict, and requires no precedence/associativity.

%%
body:
  lvals '=' rvals
;

lvals:
  lval
| lvals ',' lval
;

rvals:
  rval
| rvals ',' rval
;

rval: "var"
lval: "var"
