So it’s glibc that fails to build, but the initial “sans libc”
cross-compiler is correctly built.

This may indicate that glibc was built for N32, whereas libgcc &
co. were built for N64.
Can you run ‘file’ on libgcc.a (or one of the .o files it contains)?
Can you check in the glibc log whether a -mabi flag is passed?
You may need to explicitly add -mabi=64 for glibc. It should be
possible to do it with something like:
#:configure-flags '("CFLAGS=-mabi=64 -g -O2")
