Clang error: unknown target CPU 'pentium-m'

[Sergio Pascual <sergio.pasra@xxxxxxxxx>]

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', 'mathcode.c', '-S', '-emit-llvm', '-o', '/builddir/build/BUILD/llvmmath-0.1.1/llvmmath/mathcode/mathcode.s', '-I/usr/lib64/python2.7/site-packages/numpy/core/include', '-I/usr/include/python2.7', '-I/builddir/build/BUILD/llvmmath-0.1.1/llvmmath/mathcode/private']' returned non-zero exit status 1

    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
