Indeed, I hadn't noticed that glibc and musl define PN_XNUM, but not
uClibc. Good catch.

I guess the simplest then is to do what OpenSuse is doing:
https://build.opensuse.org/package/view_file/Kernel:kdump/makedumpfile/makedumpfile-PN_XNUM.patch?expand=1.
I had already seen it, found it not a great solution, but it's indeed
the simplest.

Best regards,

Thomas
