Thanks. That makes your suggestion below work :

make sal.all
cd sal
make clean
LDFLAGS+='--fprofile-arcs' CFLAGS+='-fprofile-arcs -ftest-coverage' \
CXXFLAGS+='-fprofile-arcs -ftest-coverage' \
CPPFLAGS+='-fprofile-arcs -ftest-coverage' make


I'll try LDFLAGS+='-fprofile-arcs' on the entire project now.
