You’d have to edit $NIXPKGS/pkgs/os-specific/linux/kernel-headers/*.nix
and change the URL in there.

Yes, I think you reported it earlier. This could be either a sign of
not enough memory, or perhaps that the consequence of trying to run an
invalid binary (such as a corrupt ELF executable.)
I think Lluís said that something must be added to ~/.nixpkgs/config.nix
to make sure the right platform setup is used, but again, I have no
expertise in MIPS64 so I can’t really help.

Nothing to worry about here.

No no. Nixpkgs is fine (well, should be); I was talking to glibc in
Guix itself (base.scm), which needs to be adjusted. You haven’t reached
the point of building packages defined in Guix yet.

glibc-ports is a glibc add-on, which adds architecture-specific code for
some platforms (glibc itself comes with support for IA32, x86_64, and
SPARC, IIRC, but support for other architectures is in the glibc-ports
tarball.)
Thanks,
