Yes, because qt is *directly* addeed to linker flags. If qt were declared in
the regular way (using "lib" rule), path to it would be hardcoded as well. But
declaring qt library in regular way requires some changes. I hope to get to
it by next week.

Since V2 did not yet recieved as much attention as V1, this feature was simply
forgotten/ignored. If this is needed, we have to devise a clean way. In the
meantime, it should suffice to change lines 40 and 41 of gcc.jam to read:
generators.register-composing gcc.archive : OBJ : STATIC_LIB(lib%) :
generators.register-linker gcc.link-dll : OBJ : SHARED_LIB(lib%) : <toolset>gcc ;
That's really bad trick, but all possible for now.
