Likely a bug in base system. Either -mabi=* should be added to LDFLAGS
similar to mips* or base Clang should stop defaulting to soft-float ABI
on a hard-float target.

share/mk/bsd.cpu.mk:

  .if ${MACHINE_CPUARCH} == "riscv"
  .if ${MACHINE_ARCH:Mriscv*sf}
  CFLAGS += -march=rv64imac -mabi=lp64
  .else
  CFLAGS += -march=rv64imafdc -mabi=lp64d
  .endif
  .endif
