Make executables position-independent

Pass -pie to the linker

before:
ruben@yourmomma: pdns (master %=)$ checksec --file pdns/pdns_server
RELRO           STACK CANARY      NX            PIE             RPATH      RUNPATH      FILE
Full RELRO     Canary found     NX enabled   No PIE         No RPATH   No RUNPATH   pdns/pdns_server
ruben@yourmomma: pdns (master %=)$ checksec --file pdns/pdns_control
RELRO           STACK CANARY      NX            PIE             RPATH      RUNPATH      FILE
Full RELRO     Canary found     NX enabled   No PIE         No RPATH   No RUNPATH   pdns/pdns_control

after:
ruben@yourmomma: pdns (master *%=)$ checksec --file pdns/pdns_control
RELRO           STACK CANARY      NX            PIE             RPATH      RUNPATH      FILE
Full RELRO     Canary found     NX enabled   PIE enabled    No RPATH   No RUNPATH   pdns/pdns_control
ruben@yourmomma: pdns (master *%=)$ checksec --file pdns/pdns_server
RELRO           STACK CANARY      NX            PIE             RPATH      RUNPATH      FILE
Full RELRO     Canary found     NX enabled   PIE enabled    No RPATH   No RUNPATH   pdns/pdns_server
