ATM, I am short on time, so just a short note without having tried to check details:

You observation probably is the result of one of two bugs in rpm:
- redhat-rpm-config kills config.sub/config.guess and replaces them with ancient
versions. This is inappropriate for binutils, gcc etc. because they ship with
much newer versions, esp. for those targettting embedded systems, which often
ship customized versions.

- %configure overrides --host, --build ...
This is wrong for cross-compilation.

The work-around to both issues is not to use %configure, but to
directly use configure with all "--*dir" options explicitly passed directly

[adding jwilson, because this bug is one of those I repeatedly had complained about]
