WIP: cross/{crossdirect,ccache-cross-symlinks}: no cc
Remove "cc" binaries/symlinks provided in both packages, because the related GCC binary is gone since the GCC-10 upgrade in Alpine.
Notably this fixes cross compiling various sxmo components (sxmo-dmenu, ...), which would fail with:
ccache: error: Could not find compiler "aarch64-alpine-linux-musl-cc" in PATH
Urgent fix, merging as soon as CI passes.
