Then you got these from the eCos 2.0 Beta distribution.

I build my own toolchains, but the ones that you've downloaded
are known to work fine.

What commands did you use to build?  Here's what I did that worked:
  % ecosconfig new innovator redboot
  % ecosconfig import /work2/ecos/packages/hal/arm/arm9/innovator/current/misc/redboot_SRAM.ecm
  % ecosconfig tree
  % make
(my eCos repository is stored at "/work2/ecos/packages")
