gcov: remove support for GCC < 4.9

Since commit 0bddd22 ("Documentation: update for gcc 4.9 requirement") the minimum supported version of GCC is gcc-4.9. It's now safe to remove this code. Similar to commit 1041553 ("gcov: Remove old GCC 3.4 support") but that was for GCC 4.8 and this is for GCC 4.9.
