firefox: Fail to build against OpenSSL 3.0

[Simon Chopin]

Hello,

As part of a rebuild against OpenSSL3, this package failed to build on one or
several architectures. You can find the details of the rebuild at

https://people.canonical.com/~schopin/rebuilds/openssl-3.0.0-impish.html

or for the amd64 failed build, directly at
https://launchpad.net/~schopin/+archive/ubuntu/openssl-3.0.0/+build/22098525/+files/buildlog_ubuntu-impish-amd64.firefox_92.0+build3-0ubuntu2.0~ssl3ppa1.1_BUILDING.txt.gz

We're planning to transition to OpenSSL 3.0 for the 22.04 release, and consider
this issue as blocking for this transition.

You can find general migration informations at
https://www.openssl.org/docs/manmaster/man7/migration_guide.html
For your tests, you can build against libssl-dev as found in the PPA
schopin/openssl-3.0.0

Looking at the build failure, the problem lies in the openssl-sys crate.
It seems the version 0.9.64 of this crate should fix the failure:

@schopin Could you try to rebuild the following firefox package against your openssl3 packages?

Rico just mentioned on IRC that Simon confirmed that building against OpenSSL 3.0 works with the firefox beta branch.
