Unable to build the project

I was trying the project, but was unable to build using the latest toolchain version.

/opt/riscv/lib/gcc/riscv64-unknown-elf/10.2.0/../../../../riscv64-unknown-elf/bin/ld: build/lib/rv32imac/libfemto.a(trap.o):(.data.riscv_intr_names+0x0): multiple definition of `riscv_intr_names'; build/lib/rv32imac/libfemto.a(memory.o):(.bss.riscv_intr_names+0x0): first defined here
