--- Comment #3 from Jan Palus <jpalus+gcc at fastmail dot com> --- I doubt this has anything to do with riscv or multilib. It's just gcc that assumes all linkers should lookup /lib and /usr/lib and skips them when passing library paths to linker: https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/gcc.cc;h=bb07cc244e30fbeccc701816db888f497d65eb08;hb=refs/heads/master#l7931 I had the same issue on arm (32-bit) so no riscv, no multilib and dropping this logic fixes the issue.
