I have made some progress on building using the more normal method, i.e.
not Docker method.

I'd like to suggest that some documentation improvements might be in order.
I'll take a stab at this once I can document to my satisfaction what work.
There are 2 key missing dependencies:
libtool
autopoint

Also what versions of NDK, build-tools, etc. are very critical.  I was
using some newer stuff and was not getting very far.

Anyway I was able to
build mythfrontend-20220812-arm-v32.0-59-gcf553e438c.apk and it runs on my
FIreTV 4K Max device.  Still not as good as Leanfront, but it's useful for
all the stuff you use mythfrontend for besides playing a recording.
