Mongo 2.4.14 is suddenly crashing on arm32v7

[ryansch]

I've honestly been waiting for this day for a while now.

The old package in the raspbian stretch repo is now crashing with the following error:

Mongo 4.4 and later have native arm64 packages but nothing for 32-bit arm. Unifi needs mongo <= 3.6.

I encountered this while trying to cut a release for 7.1.67.

We're dropping support for arm32v7.
