Subject: [PATCH] src/main: Add missing pthread header
Otherwise compilation can fail with:
main.cpp: In function 'void one_measurement(int, int, char*)':
main.cpp:226:3: error: 'pthread_t' was not declared in this scope
pthread_t thread = 0UL;
^~~~~~~~~
main.cpp:226:3: note: suggested alternative: 'pread'
pthread_t thread = 0UL;
^~~~~~~~~

Subject: [PATCH] intel_cpus.cpp: Change open parameter to const char *
ifstream::open takes std::string starting with C++11, not before.
This fixes compilation with uClibc++ and potentially other older libraries
