PR27657 addressed a similar problem but this one is slightly different and
remains unsolved:

(sid)1556:tbm@em64t: ~/src/a] cat test.c
static void sand_window_create_shape (int test) {}
static void (* const b) (int test) = sand_window_create_shape;

(sid)1557:tbm@em64t: ~/src/a] cat main.c
int main() {
}
(sid)1558:tbm@em64t: ~/src/a] make
/usr/lib/gcc-snapshot/bin/gcc -c -o main.o main.c
/usr/lib/gcc-snapshot/bin/gcc -c -g -O -o test.o test.c
/usr/lib/gcc-snapshot/bin/gcc main.o test.o
test.o:(.debug_info+0x49): undefined reference to `sand_window_create_shape'
collect2: ld returned 1 exit status
make: *** [all] Error 1
