Ok, I'll try that. Want on CC?

The good thing is, it is a new issue in 4.7 since it doesn't trigger
with 4.6:

$  make CC=gcc-4.6 drivers/ata/libata-core.o
make[1]: Nothing to be done for `all'.
make[1]: Nothing to be done for `relocs'.
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CC      drivers/ata/libata-core.o

vs

$  make CC=gcc-4.7 drivers/ata/libata-core.o
make[1]: Nothing to be done for `all'.
