Disables deadline scheduler of Linux kernel (>=3.14.x).

Disables deadline scheduler of Linux kernel (>=3.14.x).
--disable-cpu-affinity
Enables CPU Affinity between UHD/TX/RX Threads (Valid only when deadline scheduler is disabled). By defaulT, CPU Affinity is enabled when not using deadline scheduler. It is enabled only with >2 CPUs. For eNB, CPU_0-> Device library (UHD), CPU_1->TX Threads, CPU_2...CPU_MAX->Rx Threads. For UE, CPU_0->Device Library(UHD), CPU_1..CPU_MAX -> All the UE threads
Usage (first build):
oaisim (eNB + UE): ./build_oai -I -g --oaisim -x --install-system-files
Eurecom EXMIMO + COTS UE : ./build_oai -I -g --eNB -x --install-system-files
