Did you mean:

obj b : b.cpp : <use>helper ;

(note extra ':'). That use case should not be affected at all.

I think 

lib prebuilt : a : <file>prebuilt_d.a <variant>debug <threading>single
<use>a ;

should work. At least 'unix-prebuilt-lib-generator' in unix.jam sets 
dependency from what's mentioned in <file> to sources.
