The reason I think we should use gcc's "crtstuff.c" versions is that
it will make it easier for us to keep in sync with any future changes
they make.

It seemed like a good idea at the time. :-) What is the problem --
is it that libc_r is initialized at the wrong time? What would you
suggest as a better method for initializing the library? I'd hate to
introduce a bunch of "if (!initted) { ... }" checks, since those add
runtime overhead on every call.
