Package: liburcu Version: 0.8.4-2.1 Severity: serious
If your package is built on a system with an armv7 processor it builds for armv7. Since debian armel targets armv4t but is now built on armv7 hardware this is a major prboem. It's also a problem for rasbian.
Also I notice the flags are selecting coretex-a9 specficially rather than a generic armv7-a. I don't know if that is a problem on debian armhf or not (that is I don't know if there are any instructions specific to that core that are not available more generally)
The attatched patch disables the offending flags completely. It has been uploaded to raspbian, no intent to nmu in Debian.
