Fix for not visible pthreads function with glibc 2.15

Browse source 
Linking error will appear:

Linking CXX executable ../../openmw
/usr/bin/ld: CMakeFiles/openmw.dir/__/__/components/bsa/bsa_archive.cpp.o: undefined reference to symbol 'pthread_mutexattr_settype@@GLIBC_2.2.5'
/usr/bin/ld: note: 'pthread_mutexattr_settype@@GLIBC_2.2.5' is defined in DSO /lib/libpthread.so.0 so try adding it to the linker command line
/lib/libpthread.so.0: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

if we don't add explicitly pthreads library to linker flags
after update glibc to version 2.15 on (Arch) Linux.
