I am not 100% sure I understand. Do you mean if it's possible to same action, 
say "gcc.link" for linking both application and shared libraries. I think 
this should be possible:

generators.register-linker gcc.link : LIB OBJ : EXE : <toolset>gcc ;
generators.register-linker gcc.link-dll : OBJ : SHARED_LIB : <toolset>gcc

can become

generators.register-linker gcc.link : LIB OBJ : EXE : <toolset>gcc ;
generators.register-linker gcc.link : OBJ : SHARED_LIB : <toolset>gcc

the only problem is that "gcc.link" here is used to two purposes: identifying 
the generator and naming the rule used to set up build actions. This can lead
to confusion in some code (toolset inheritance, in particular), but that's not
something hard to fix.
