Makefile:2156: recipe for target 's-output' failed
I noticed that much VSX-related work have been done in this release cycle,
according to ChangeLog. The last versions that worked correctly for me were
5.1.0 and 6.0.0-alpha20150412 (of 5.1 branch and trunk, respectively), and
after that I've stopped doing my own weekly builds. I still have to find out
when the issue have started showing up, given that I now have half a year wide
window.
