I think it would be good to fix this in the gcov tool. When I think
of distribution kernels the source usually ends up in a different
place in the packages than the kernel was originally compiled. So
it would be good to extend gcov here or let it search in well known
locations first (/usr/src/linux, /usr/src/debug/...).
