Clang error: unknown target CPU 'pentium-m'

[Sergio Pascual]

Hi, I need help with an error of clang in mock.

I have this package review:

https://bugzilla.redhat.com/show_bug.cgi?id=1012169

That builds OK in mock in a x86_64 machine.

A scratch build in koji fails for x86_64 (and probably others)

http://koji.fedoraproject.org/koji/taskinfo?taskID=5992058

with the following error (
http://kojipkgs.fedoraproject.org//work/tasks/2060/5992060/build.log)

error: unknown target CPU 'pentium-m'
ERROR:root:Command '['clang', '-O3', '-march=native', '-c',

    cwd=mathcode)
  File "/usr/lib64/python2.7/subprocess.py", line 542, in check_call
    raise CalledProcessError(retcode, cmd)

I imaging that -march=native is returning the arch of the builder, that is
not supported. How can I make this work?

Regards, Sergio
