Not really.

Static build works for me, including building perf-read-vdso32 statically,
so I am not sure what the problem is?

The static build stops for me way before getting to these utilities, so
I don't know, I fixed an unrelated problem, but Jiri is the one having
trouble in this one, Jiri, can you post the output of the build when it
fails?
