According to the doc (info "(gcc)Debugging Options") it is required.
See also this example (with GCC 4.2.4):
$ cat > t.c <<EOF
int main (int argc, char *argv[]) { return 0; }
EOF
$ gcc --coverage -c t.c
$ gcc t.o
t.o: In function `global constructors keyed to 0_main':
t.c:(.text+0x43): undefined reference to `__gcov_init'
t.o:(.data+0x24): undefined reference to `__gcov_merge_add'
collect2: ld returned 1 exit status
$ gcc --coverage t.o
[ success ]

I don't think `-O' matters. I don't think `-g' is required to get
useful source location information.
Thanks,
