This test program is a pthread application, while Makefile has no flags for linker about pthread library. This can cause below error.

$ make pcm-multi-thread CCLD pcm-multi-thread /usr/bin/ld: pcm-multi-thread.o: undefined reference to symbol 'pthread_cancel@@GLIBC_2.2.5' //lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status Makefile:523: recipe for target 'pcm-multi-thread' failed make: *** [pcm-multi-thread] Error 1

This commit fixes the bug by adding a corresponding flag.
