Okay, I’m not sure what the implications are this for you. We have a test infrastructure that tries to download, build, and link liburcu using a cross compiler for 32-bit arm platforms, but it fails because of this check. I will try and figure out how to get a binary version of liburcu installed permanently somewhere that the cross compiler toolchain can find.

Thanks,
Luke
