Think of RedBoot as an eCos application that's providing its own
implementation of printf. It does not need libc, so you should not
have that package included.

When you prepare a RedBoot build tree, do it like this:

 ecosconfig new <target> redboot

Not by starting from the default template and adding the redboot
package.
