Look at the strace output.  If the sequence is really

  llseek(...) = 0
  write (...) = EINVAL

then this is a new quirks in the kernel.  The write() syscall mustn't
return this.

In this case you can ignore the error or better finally drop the 2.2
kernel.

Copy and paste the commandline make builds to create the test binary
and add -Wl,-dynamic-linker,BUILDDIR/elf/ld.so,-rpath,BUILDDIR.
