Subject: compilation with plugins

Hello,

I am not able to compile anything with last Friday's linux-next:

commit 8f6027f7e808ed7c1fd8c8d37fc7a5076c683c4f
Author: Stephen Rothwell <sfr@...b.auug.org.au>
Date:   Thu Jun 9 16:31:36 2016 +1000

After running make allyesconfig, I get the following when trying to 
compile any file:

cripts/Makefile.gcc-plugins:17: warning: cannot use CONFIG_KCOV: 
-fsanitize-coverage=trace-pc is not supported by compiler

-------------------

gcc --version gives:

gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

Is there some way to disable the use of plugins, or to solve the problem 
in some other way?

thanks,
julia
