Subject[PATCH] tools: Fix pthread flag for Makefile of trace-agent used by virtio-trace
Date
pthread flag should not be -lpthread but -pthread using gcc. The -lpthread
links the external multithread library. On the other hand, the -pthread manages
both the gcc's preprocessor and linker to be able to compile with pthread.
