kbuild: setlocalversion: print error to STDERR
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.
