GCC's gcov instrumentation (-fprofile-arcs -ftest-coverage) has no
architecture-specific runtime requirements. Enable GCOV_PROFILE_ALL
support for Alpha to allow whole-kernel code coverage analysis.

Assisted-by: Claude:claude-opus-4-6
Signed-off-by: Matt Turner <[email protected]>

Also mark Alpha as "ok" in the gcov-profile-all feature matrix.
