Can't compile uclibc for newer kernels (missing syscalls)

Question

I'm having an issue building uclibc for rv32. It is missing a lot of syscalls. I have a few of the errors listed below.

What are things to look for and approaches to take when trying to determine why uclibc is improperly trying to use syscalls. I am on uclibc-1.0.45 and Linux 6.8-rc4.

Is there some general approach to take in situations like this?
