`ccache` ships in the toolchain as of ftl-build v2.25 (pi-hole/docker-base-images#184), so the temporary `apk add` this branch carried can go. Only the source of the binary changes - the cache is still configured and used exactly as before. Note that moving to a new image invalidates every cache entry once, as `CCACHE_COMPILERCHECK=content` hashes the compiler and v2.25 is a fresh build of the toolchain. The first run after this recompiles from scratch, and the ones after that hit again. Signed-off-by: DL6ER <dl6er@dl6er.de>
