Subject: [PATCH 3.16 16/63] kbuild: setlocalversion: print error to STDERR

3.16.81-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Wolfram Sang <wsa@...-dreams.de>

commit 78283edf2c01c38eb840a3de5ffd18fe2992ab64 upstream.

I tried to use 'make O=...' from an unclean source tree. This triggered
the error path of setlocalversion. But by printing to STDOUT, it created
a broken localversion which then caused another (unrelated) error:

"4.7.0-rc2Error: kernelrelease not valid - run make prepare to update it" exceeds 64 characters

After printing to STDERR, the true build error gets displayed later:

  /home/wsa/Kernel/linux is not clean, please run 'make mrproper'
  in the '/home/wsa/Kernel/linux' directory.
