Also, that particular binutils commit doesn't actually seem to fix things - there is still Extra PLT reference: libc.so: memset with mainline GCC / binutils. Could one of the RISC-V people please investigate why there are still those failures with build-many-glibcs.py, for riscv32-linux-gnu-rv32imac-ilp32, riscv32-linux-gnu-rv32imafdc-ilp32 and riscv32-linux-gnu-rv32imafdc-ilp32d when using mainline GCC and binutils? https://sourceware.org/pipermail/libc-testresults/2020q3/006734.html -- Joseph S.
