E3-863: Revert https://github.com/epics-base/epics-base/commit/0d2228b5362fd721c94408065908adfbdf0d840e
In EPICS base, the architecture powerpc64-linux
was added in this
commit. However, it interferes with our use of it at ESS. Some discussion
was had as to whether or not we should simply adopt the architecture
ppc64
at ESS entirely, but for simplicity, for the time being, we
will just revert this change.
