## Soft-lock if `sccache` is preinstalled in chroot
Apparently, some packages automatically use ccache/sccache if it is installed in
the chroot, and in some cases, causes a soft-lock during a build. It is
recommended to not have ccache/sccache preinstalled in the chroot and to just
let the aur-helper-script install it when necessary.
For example, when building `tenacity-git` with sccache preinstalled, the build
will hang after the final build step. Apparently, killing the running `sccache`
process stops the soft-lock in this case.
