The log message (in rev.1.16) doesn't give a reason. I think it was
changed long before the c++rt0.o problem was noticed.
I want this fixed completely (correct dependencies for all crt0.o's and
libraries). Perhaps breaking it a little more will annoy someone enough
to fix it properly.

No.

Everything is supposed to depend in ${LIBCRT0} and all relevant static
libraries. Of course, this is wrong for shared libraries.
