That's not what these are.

Because downloading 100 MB of kernel source and extracting it to a far
larger tree just to get the headers isn't really fun.

The linux-headers alternative has been supported for a long time; it
just wasn't default because the default had been untouched for a long
time. When it became necessary to bump the default (because old
headers are incompatible with musl 1.2) I switched to it.

If this is the problem, you can switch to using the full kernel
sources via LINUX_VER=4.19.90. I'd like to debug the root cause and
get it fixed, but unless there's a quick fix I'll just change the
default to LINUX_VER=4.19.90 for now.
