   External Bug ID: Red Hat Bugzilla 1671064
    Classification: Fedora

libldac request: https://bugzilla.redhat.com/show_bug.cgi?id=1671064

Failed Koji build:
https://koji.fedoraproject.org/koji/taskinfo?taskID=32827186

Throws error because of upstream code:
#if __BYTE_ORDER == __LITTLE_ENDIAN
/* stuff */
#else   /* __BYTE_ORDER */
#error unsupported byte order
#endif

Original code here:

I'd like an excludeArch here since it builds fine on all other arches. Thanks!
