Yes. I don't know how that got there ;-/ Errors at this point will in 
practice be ignored, though, so the rpm is still built successfully.

You are probably right. That would make sure that the binutils etc. just 
built would always be used in the subsequent steps, even if a version of 
the cross compiler was installed already. Notice, however, that the 
build system will always look for versions that are specific to the 
cross compile target host, of these tools, so variants for other 
platforms that may be installed will not be allowed to interfere.

Thanks for pointing this out.
