Hi Guenter,

First bad commit (maybe != root cause):

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head:   de06dbfa7861c9019eedefc0c356ba86e5098f1b
commit: 398c7500a1f5f74e207bd2edca1b1721b3cc1f1e MIPS: VDSO: Fix build error with binutils 2.24 and earlier
date:   3 months ago
config: mips-jmr3927_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
        chmod +x ~/bin/make.cross
        git checkout 398c7500a1f5f74e207bd2edca1b1721b3cc1f1e
        # save the attached .config to linux build tree
        make.cross ARCH=mips
