From d5bfb6b3814b2c9cd83e9395a60fc4b4e42a242d Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Fri, 8 Jun 2012 01:48:57 +0200 Subject: 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.
