The kernel remembers who has compiled it, when, and where. If you 
compile it yourself you'll be pleased to see your username in 
/proc/version. You can also add some tag to the kernel version It is 
also possible to add some tag to the version of gcc if you compile it 
yourself, and it will appear when you invoke 'gcc --version'.

     As long as Devuan keeps Debian packages for kernel and gcc, you're 
going to see that they have been compiled by Debian devs. And Devuan, 
for the moment only modifies packages which need to, in order to get rid 
of systemd dependency. This does not involve gcc, and not yet the kernel.
