That is correct, as I painfully found out today.
It's the first day I've ever tried to do a "make world" from the
-current sources, and I've run into several problems. I'm using
DESTDIR, because I don't want to wipe out my existing (working) system,
of course. I'll report more details, once I get through it all.

And, don't forget that you have to make "cc" find its helper programs
(such as "cc1") in the right places. And, "ld" has to look in the right
places for its libraries, and for crt0.o, etc. And on and on. There are
lots of problems.
I don't think an ldconfig will be necessary, as long as LD_LIBRARY_PATH
is set properly.
Here is a shell script I am working on that solves almost all of the
problems that I've encountered so far today. (I also had to edit the
top-level Makefile. It does something that requires c++rt0.o, before
that file has been built or installed.) (Diffs at 11!) I'm optimistic
that this approach will work, eventually.
