Match whole words when changing .config options

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.

Decide whether to use the host or target ldconfig based on an availability check instead of internal/external toolchain selection. An external toolchain may very well provide an ldconfig while the host's one may fail.
External toolchain generated by Gentoo crossdev:

$ LC_ALL=C i686-pc-linux-uclibc-ldconfig -r output/target/; echo $?
i686-pc-linux-uclibc-ldconfig: skipping /usr/lib: No such file or directory
0

vs. the host (x86_64-pc-linux-gnu) version:

$ LC_ALL=C /sbin/ldconfig -r output/target/; echo $?
/sbin/ldconfig: Can't open configuration file
output/target/etc/ld.so.conf: No such file or directory
/sbin/ldconfig: Can't open cache file /var/cache/ldconfig/aux-cache
: No such file or directory

Committed both, thanks.

In the future, don't forget to sign off on your patches (use -s).
