pg_autoctl: unrecognized option on Alpine Linux

[asafza]

When running the following Dockerfile

FROM alpine:3.15.4

RUN apk add postgresql-dev openssl-dev krb5-dev ncurses-dev \
    build-base linux-headers \
    libxml2-dev lz4-dev libxslt-dev libedit-dev readline-dev \
    postgresql14 git

RUN git clone --depth 1 --branch v1.6.4 https://github.com/citusdata/pg_auto_failover && \
    cd pg_auto_failover && \
    make install -j8

RUN /usr/libexec/postgresql14/pg_autoctl create monitor \
    --auth trust \
    --ssl-self-signed \
    --pgdata monitor \
    --pgctl /usr/bin/pg_ctl

The pg_autoctl command results with

/usr/libexec/postgresql14/pg_autoctl: unrecognized option: auth
/usr/libexec/postgresql14/pg_autoctl: unrecognized option: ssl-self-signed
/usr/libexec/postgresql14/pg_autoctl: unrecognized option: pgdata
/usr/libexec/postgresql14/pg_autoctl: unrecognized option: pgctl
pg_autoctl: pg_auto_failover control tools and service
usage: pg_autoctl [ --verbose --quiet ]

See also #223 ; where my last question remains. I can't see how to fix getopt_long parsing with POSIXLY_CORRECT in a way that works both on GNU libc, macos libc, and also Alpine libc. Or maybe I'm just missing something? help!

Note to myself: I could reproduce the problem from source with the following variation on the provided Dockerfile (thanks @asafza ), and failed to fix it when commenting out the main.c call to setenv("POSIXLY_CORRECT", "1", 1);.
