makefile variable overrides for each directory variable is required by

Sharing Defaults

# Version 1.1pre13 May 1 2016
# Version 1.1pre15 September 2 2017
* Detect when the machine is resuming from suspension or hibernation.
* When an old PID file is found, check whether the old daemon is still alive.
* Remember scope_id for IPv6 addresses when sending UDP packets to link-local
addresses.
* Ensure compatibility with OpenSSL 1.1.
* Only log about dropped packets with debug level 5.
* Warn when trying to generate RSA keys less than 2048 bits.
* Use AES256 and SHA256 as the default encryption and digest algorithms.
* Add DeviceType = fd to support tinc on Android without requiring root.
* Support PriorityInheritance for IPv6 packets.
* Fixes for Solaris tun/tap support.
* Add a configurable expiration time for invitations.
* Store invitation data after a succesful join.
* Exit gracefully when the tun/tap device is in a bad state.
* Add the LogLevel option.
* AutoConnect now actively tries to heal split networks.
Thanks to Etienne Dechamps, Rafał Leśniak, Sean McVeigh, Vittorio Gambaletta,
Dennis Lan, Pacien Tran-Girard, Roman Savelyev, lemoer and volth for their
contributions to this version of tinc.
# Version 1.1pre14 May 1 2016
