commit: https://git.buildroot.net/buildroot/commit/?id=da34a889d218ba5722774a769842ed08a64279ae
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This upstream patch fixes the build error produced by building for
powerpc 32bit after the glibc bump to 2.26 with the following internal
toolchain config.

gcc5.4.0
glibc2.26
bin2.28.1
linux4.1.43

Failure log:
  CC	net/proto-ipv4.o
net/proto-ipv4.c: In function ‘ip_setsockopt’:
net/proto-ipv4.c:231:49: error: ‘UIO_MAXIOV’ undeclared (first use in this function); did you mean ‘_IO_MAGIC’?
   so->optlen = rnd() % sizeof(unsigned long)*(2*UIO_MAXIOV+512);
                                                 ^~~~~~~~~~
                                                 _IO_MAGIC
