Hi Javi,

[auto build test WARNING on thermal/next -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

config: m32r-m32104ut_defconfig (attached as .config)
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
