I tried to change the kernel config file and then rebuild the kernel, but it 
fails like this on two up to date stable systems:

# gcc-config -l

Why is this happening and how can I fix it?  Running on 4.9.4 
doesn't change anything.  :-/

Am I supposed to emerge a later version gentoo-sources to be able to build a 
kernel with gcc-5.4.0?
