Following errors pop up each time the Kubernetes is built with golang-1.7.3-1.fc26 on ppc64le:

Comment from  Lynn A. Boger 2016-11-28 14:24:30 CST

This problem is due to a golang linker issue that happens when binaries get too big on RISC platforms like ppc64le and arm.  With golang, linking can be done externally (i.e., system linker) or internally (golang linker), which means fixes are needed for both types of linking.

The patch that had been provided for go 1.7 ppc64le fixes the external linking case.
I currently do not have a patch for use with internal linking in go 1.7.
The golang community did not accept a backport of these patches because they were considered too risky.

Fixes for this problem for both internal and external linking are upstream and will be in go 1.8 when released in Feb. 2017.

As a workaround with go 1.7.3-1.fc26, the setting of
GOLDFLAGS='-linkmode=external'
when doing the build could be used to force all binaries
to be built with external linking, and that avoids the link error.
