Subject: undefined reference to `printk'

Hi Peter,

It's probably a bug fix that unveils the link errors.

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head:   3684b03d8e9a889eda94ee74421959a9d55e5e19
commit: 63a3f603413ffe82ad775f2d62a5afff87fd94a0 timeconst.pl: Eliminate Perl warning
date:   3 years, 6 months ago
config: m32r-allnoconfig (attached as .config)
compiler: m32r-linux-gcc (GCC) 4.9.0
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 63a3f603413ffe82ad775f2d62a5afff87fd94a0
        # save the attached .config to linux build tree
        make.cross ARCH=m32r 

All errors (new ones prefixed by >>):

   arch/m32r/kernel/built-in.o: In function `default_eit_handler':
>> (.text+0x51c): undefined reference to `printk'
   arch/m32r/kernel/built-in.o: In function `default_eit_handler':
   (.text+0x51c): relocation truncated to fit: R_M32R_26_PCREL_RELA against undefined symbol `printk'
