Hi Purushotham,

CONFIG_FEATURE_SYSLOG is a hidden option in busybox' Kconfig. You can
disable it only by disabling all options that select it. This is the
list of packages that select FEATURE_SYSLOG taken from manuconfig
help:

Symbol: FEATURE_SYSLOG [=y]
    Selected by: INIT || GETTY || LOGIN || PASSWD || SU || SULOGIN ||
FEATURE_MOUNT_NFS && MOUNT || CROND || DEVFSD || NAMEIF || FAK
