[Buildroot] [git commit master 1/1] Match whole words when changing .config options

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=0383d48a5e61db900171ae74d4d2dfe30c420d04
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Make KCONFIG_{ENABLE,DISABLE,SET}_OPT match whole words only.
Fixes that BR_INET_IPV6 enables CONFIG_IPV6 in the kernel's
.config, but also nukes everything with "CONFIG_IPV6" in its name, e.g.
CONFIG_IPV6_PRIVACY.  This in turn causes any IPv6 options in a custom
kernel .config to be lost and oldconfig going interactive.
