That's what I thought, but not found.

OK.  Well, I've a couple of arguments for it which I'd like weighed
against the other solutions I suggested:

First, as I already said, we could provide support for other make
infrastructures as well.  Second, the proposal did not include removing
compile mode from `libtool', so nobody really loses.  Third, it may
enable us to actually profit from the fact that we don't need to compile
both PIC and non-PIC in some cases.

If you ask me, the increased number of special cases does not really add
much to the overall complexity.  Libtool already has an abundance of
special cases, many of which are more difficult to check.

The bug report by the libjava people suggests a possible speedup of
almost 2/3 resp. 5/6 for their case.  To me, this proposal "just sounds
like the right thing", but I am certainly open to arguments.
