Subjectmore build problems with "Makefile: move stackprotector availability out of Kconfig"
Hi Kees,

On my test box, current linux-next kernels fail to build due to the
patch that introduces CONFIG_CC_STACKPROTECTOR_AUTO, with my mainline
builds up to gcc-5.5.0. gcc-6 and higher work fine, as
scripts/ returns 'y' for those.

Using the compilers provided by Ubuntu (4.6/4.7/4.8/4.9), everything
also works as expected, so my interpretation is that mainline gcc did
not enable the stack protector until gcc-6, while distributions did.

Do you agree with that interpretation?

If yes, is there anything we can do about it? I can probably rebuild
my collection of x86 compilers to enable stackprotector if necessary,
but I wonder how many other people will run into the same problem.
