coz requires linking in order to get results

[jesperpedersen]

If I do

gcc -O0 -fno-omit-frame-pointer -gdwarf-4 -lpthread -o threads threads.c
coz run --- ./threads

profile.coz will only contain

startup time=1570708262628386257
runtime time=26558496795
samples location=/path/to/threads.c:15  count=1005
samples location=/path/to/threads.c:17  count=710
samples location=/path/to/threads.c:19  count=326
samples location=/path/to/threads.c:21  count=442
samples location=/path/to/threads.c:42  count=22764
samples location=/path/to/threads.c:44  count=3733
samples location=/path/to/threads.c:66  count=2435
samples location=/path/to/threads.c:68  count=383

However, if I explicit link against coz with

gcc -O0 -fno-omit-frame-pointer -gdwarf-4 -lpthread -lcoz -Wl,-rpath,/usr/local/lib -o threads threads.c

I do get results in profile.coz threads.txt
