coz requires linking in order to get results

[Jesper Pedersen]

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
