[V2] Multiple linking stage

Hi.
I tried to use Boost.Build V2 to build applications for some custom embedded 
system. The building process uses modified GCC tools and has complicated 
linking stage whch consist of three steps:
1) *.o and *.a files are linked to app.xxx,
2) app.xxx and *.a are linked to app.yyy (with linking scripts different 
from previous step),
3) app.yyy is converted to app.zzz, that is an executable.

I'm writing custom toolset module and my question is how to write a link 
rules/actions correctly.
Should I use a generators? I tried this code, but I don't like it and it 
does't work:

type.register XXX : xxx ;
generators.register-composing egcc.xxxlink : OBJ SEARCHED_LIB STATIC_LIB 
: XXX : <toolset>egcc ;

type.register YYY : yyy ;
generators.register-composing egcc.yyylink : XXX SEARCHED_LIB STATIC_LIB 
: YYY : <toolset>egcc ;

generators.register-standard egcc.link : YYY : EXE : <toolset>egcc ;

Truly yours, Max Stroev
