I want to compile hqc using llvm's clang and ld.

llvm-project-19.1.0.src/build/bin/clang  --target=hexagon -mv73 -mhvx -std=c99 -integrated-as -I /hexagon/5.5.1.1/tools/HEXAGON_Tools/8.7.06/Tools/target/hexagon/include -Wall -g -I. -I./common -I./hqc-256 -I./hqc-256/clean -I./.vscode -c test_kem.c -o test_kem.o

llvm-project-19.1.0.src/build/bin/ld.lld test_kem.o common/aes.o common/fips202.o common/nistseedexpander.o common/randombytes.o common/sha2.o common/sp800-185.o hqc-256/clean/code.o hqc-256/clean/fft.o hqc-256/clean/gf2x.o hqc-256/clean/gf.o hqc-256/clean/hqc.o hqc-256/clean/kem.o hqc-256/clean/parsing.o hqc-256/clean/reed_muller.o hqc-256/clean/reed_solomon.o hqc-256/clean/shake_ds.o hqc-256/clean/shake_prng.o hqc-256/clean/vector.o -o program -L /hexagon/5.5.1.1/tools/HEXAGON_Tools/8.7.06/Tools/target/hexagon/lib/v73/*.a  

use this command to link,get this problem

ld.lld: error: duplicate symbol: .CONST_3FF0000000000000

make: *** [Makefile:46: program] Error 1

if I add --allow-multiple-definition this option,then I get
