Implement optional timezone change detection for local time libc functions. This is disabled by default; set WITH_DETECT_TZ_CHANGES to build it. Reviewed By: imp Sponsored by: NetApp, Inc. Sponsored by: Klara, Inc. X-NetApp-PR: #47 Differential Revision: https://reviews.freebsd.org/D30183

It is better to disable the INCLUDE_CONFIG_FILE option so as not to include the kernel configuration file. This allows to redure kernel infoleaks and thus to complicate the life of the attacker which we have already deprived of direct access to the kernel [1].
