That's what my patch does. It would be good if Joel could test on
i386-rtems before comitting (as I will on Solaris/SPARC and x86, of
course).

No, if a t-* fragment sets CUSTOM_CRTIN, it's expected to provide its
own crt[in].o rules, just like the existing CUSTOM_CRTSTUFF does. If
crt[in].o is not included in extra_parts, the generic rules are
unused/harmless.

True, but that's the sort of copy-and-paste programming I'd like to
reduce with this series of patches.
