scripts/config: add option to undef a symbol
It is currently possible to enable, disable or modularise a symbol. Also, an undefined symbol is reported as such. Add a new command to undefine a symbol, by removing the corresponding line from the .config file. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Signed-off-by: Michal Marek <mmarek@suse.cz>
