This reverts commit 55e4ec054c21b9164e10c323a5f0afff1deb1d67.

There are still build failures in parallel builds:
    http://autobuild.buildroot.org/results/9a0/9a0fc1064010a658155e6a18ec72e0e3c58ec7f6/
    http://autobuild.buildroot.org/results/c28/c28064f383da1f577bd9227d004f1939daf4579f/
    http://autobuild.buildroot.org/results/218/2180b9d900b27103acc92a2932f7ffa560b04831/
    and so on...
