gcov-kernel: Make gcov work on vanilla gcc again.
Commit "gcov-kernel: patch for Android toolchain 4.4.x support" broke
support for gcov on vanilla gcc. Introduce #ifdefs to make it work on
both of them.
Since the gcov ABI for Android gcc is different, the build system
must set CONFIG_GCOV_TOOLCHAIN_IS_ANDROID when compiling with an
Android toolchain.
Also remove a few magic numbers from the original gcov code and fix a
unused function warning.
