Not sure. The same sequence of steps works for me on Centos.
What GCC/GNAT version are you using and what OS?

GNATs based on GCC 2 (eg, GNAT 3.15p) use the .bb and .bbg files, and
the output would be in .da files. GNAT GPL 2006 (on Mac OS X at any
rate) uses the .gcno and .gcda files.

Ah! On this machine I get

$ gnatmake -fprofile-arcs -ftest-coverage helloworld.adb -f
gcc -c -fprofile-arcs -ftest-coverage helloworld.adb
gnatbind -x helloworld.ali
gnatlink helloworld.ali -fprofile-arcs -ftest-coverage

so the gnatlink call is different ...
