I don't know whether you'd consider this more elegant, but I think you'll agree 
this being simpler:

rule bison-obj ( name : sources * : reqs * : def-build * : usage-reqs * )
{
   obj $(name) : $(sources)
                     : $(reqs) <define>SOME_MACRO <include>some/path
                     : $(def-build)
                     : $(usage-reqs)
   ;
}

bison-obj bison1
    :  bison1.yy
    : <bison.prefix>pre1
    ;

bison-obj bison2
    :  bison2.yy
    : <bison.prefix>pre2
    ;

Or perhaps as simple as this?

local bison-reqs = <define>SOME_MACRO <include>some/path ;

obj bison1
    :  bison1.yy
    : <bison.prefix>pre1 $(bison-reqs)
    ;

obj bison2
    :  bison2.yy
    : <bison.prefix>pre2 $(bison-reqs)
    ;
