make-*: include musl build in make-binaries
Ctr actions: use github runners to provide bootstrap erlang
- adjust make-binaries script to use github runners' installed erlang
for bootstrapping
- this reduces the need to build an unnecessary toolchain for glibc
based binaries
Update zlib to 1.2.13 to address CVE-2022-37434
Also change zlib download to use archive URL so builds do not fail
when specified version is no longer the current version
Don't break the (currently nonexistent) case where a dependency's
rebar.config file specifies LDFLAGS before and after "-lstdc++", such as
"-lfoo -lstdc++ -lbar".
The tools/make-binaries script creates self-contained OTP releases for
Linux/x64 and Linux/arm64 systems. All optional ejabberd features are
supported. Erlang/OTP, Elixir, and all dependencies are downloaded and
built from source (using crosstool-NG). The generated binaries depend
on glibc 2.17 or later, all other external libraries are linked
statically.
The script should work on any non-ancient Linux/x64 system and requires
just a few common development tools (to bootstrap crosstool-NG).
The release is installed by creating an "ejabberd" user, extracting the
archive into /opt, and moving the systemd unit (or init script) into
place.
