[Pkg-nginx-maintainers] Bug#996788: libnginx-mod-http-lua: Please enable luajit for arm64

[Noah Meyerhans]

Package: libnginx-mod-http-lua
Severity: wishlist
Tags: patch

Currently libnginx-mod-http-lua declares architecture-specific build-deps to
choose either liblua5.1 or libluajit-5.1.  For the arm64 architecture,
liblua5.1 is used even though luajit is availabile on this architecture.

I've locally built nginx with the following change to debian/control and
performed basic testing of the resulting packages:

Please enable libluajit for the arm64 builds of libnginx-mod-http-lua.  Let me
know if you have concerns about this request or would like to see further
evidence of testing.

Thanks
