arbor: Architecture support: build failures on architectures other than x86_64

While building for Fedora, I’ve noticed that arbor fails to build on all architectures other than x86_64. These other architectures we currently build in Fedora for are: armv7hl, i686, aarch64, ppc64le, s390x.

The crash log says:

It seems to be the same error on all these failing arches. The complete build logs can be found here: https://koji.fedoraproject.org/koji/taskinfo?taskID=39482950.

Does arbor support these arches? (We can exclude them from the Fedora build if it does not.) I use -DARB_ARCH=native in the builds, if that makes a difference.

Thanks,
