Implement /proc/built-in file similar to /proc/modules

This series implements a possibility to show the list of built-in drivers to userspace. The names of drivers will be the same as when they are modules. So, if your system has "loop" driver then it appears either in /proc/modules or in /proc/built-in and userspace will be able to know about this.

Now this is impossible. The only way to get kernel configuration is /proc/config.gz, but CONFIG_* names can change from time to time. Module names are more or less standardized.

kbuild: Make targets names tree-wide unique on x86
core: Save list of built-in drivers names
core: create /proc/built-in file to show the list of built-in drivers
