Ouch. Quite an endeavor, I suppose.

Oh. I dropped the ball on this issue, but I hope to get back to it Real
Soon Now.

You need to have both glibc-mipsel.../include and
linux-libre-headers-mipsel.../include in CROSS_CPATH. Can you check
whether this is the case.
Another possibility is that it’s picking native headers instead of
cross-headers for some reason. To check whether this is the case, you
can look at the output of the mipsel-...-gcc --verbose, or just strace
that and look at the .h files it opens.
TIA,
Ludo’.
