Comment:
This type of issue has bitten me not too long ago as well. The `(error 19)` is the only indication that there is indeed a cyclic dependency and we need to identify and eliminate it.

Edit: I'm confused: just tried with my locally built repository and there I can build libevent w/o error.
Edit2: The first thing I did to get `armv5tel-musl` built is to cross build the `base-chroot` package. Perhaps you can try that and then build with `-N` option to use your local repository's `arm5tel-musl` packages.
