3 years ago I am unable to reproduce your specific problem on my Mac Mini M1 with Big Sur.
libiberty.a is created with native ar and ranlib from natively compiled object files. From your log:
gcc -c -DHAVE_CONFIG_H -g -O2 -I. -I../../libiberty/../include -W -Wall -Wwrite-strings -Wc++-compat -Wstrict-prototypes -pedantic ../../libiberty/pex-unix.c -o pex-unix.o
rm -f ./libiberty.a pic/./libiberty.a
ar rc ./libiberty.a \

ranlib ./libiberty.aIf this results in a library with "unknown-unsupported" format, then there has to be something wrong with your XCode installation...
Did you try using the docker?

When running the toolchain script and building binutils, linking of several executables fail with errors similar to this: ../libiberty/libiberty.a, building for macOS-x86_64 but attempting to link with file built for unknown-unsupported file format.
See attached build log file.
