You _must_ have done something beyond what you've said.  RedBoot does
not use the stdio package (which is where that error is coming from).

Your steps should be (in a _clean_ directory):
  % ecosconfig new ipaq redboot
  % ecosconfig import
${ECOS_REPOSITORY}/hal/arm/sa11x0/ipaq/current/misc/redboot_ROM.ecm
  % ecosconfig tree
  % make

If you're using the ConfigTool, make sure you start from a clean build
directory and then choose the 'redboot' template.
