It is an autobuilder issue indeed, but it was not detected the date I
wrote the patch. The autobuilder issues concerning swupdate until that
date where Lua 5.1/LuaJIT related. I noticed the issue using the Linaro
 Toolchain for armhf.

There is now a report of an autobuilder from yesterday:
http://autobuild.buildroot.net/results/1c3/1c349cc5904868e4def292b9fbfa
164828e46156/

Not all toolchains are producing the issue (only glibc ones?):
