Source package libgda-5.1.2-2.el7.1.src.rpm used by EPEL7 does not support ppc64le (little endian) Is it possible to have a newer version supporting this architecture ? note that libgda-5.2.2-3 contains changes needed to support ppc64le.
The same applies for aarch64. Given that GNOME has been rebased to 3.14 in RHEL 7.2, I believe rebasing libgda epel7 to the f21 branch would make the most sense. Otherwise, the patch for these new arches is quite minimal.
