Ian, thanks.

Which versions qualify as "recent" above? GCC 3.4, or 4.0, or both?

Since at least 3.3.

I think binutils and gdb acquired this talent around Jan 2003 (see http://sources.redhat.com/ml/binutils/2003-01/msg00065.html, http://sources.redhat.com/ml/gdb-patches/2003-01/msg00380.html) so you might need newish versions of them, too.

Is there any documentation on how the new packaging mechanism works?

It's not a new packaging mechanism and it doesn't require any adjustment; the entire thing should Just Work.

If you happen to need to be able to do this with old tools, you can try http://kegel.com/crosstool/current/fix-embedded-paths.c

Excerpt:
 Program to fix embedded paths in files.
 Useful especially for gcc < 3.0 and binutils < 2.14, which
 do not work if you move them after installation;
 running this program fixes the paths and lets the programs work again.

I use this to be able to build crosstool rpms of old tools
without having write access to the final install location, and it seems to work.
(Actually, I use it for new tools, too, 'cause it doesn't seem to hurt,
and it's nice to have all the embedded paths right just in case.)
