I tried adjusting the flags to -Oz (not recognized) or -Os and it still
didn't fit. What device(s) use the imx8mq? Is that the chip in the
Librem 5?

I've added some people who might be interested in the chip. I suppose at
first glance I'd prefer using the vendor fork (assuming there's some
form of ongoing maintenance) over keeping the older version.
