risc-v 64-bit stubs build successfully in developer environment

This is the "bottom half" to add support for riscv64 to UPX.
Need update to stubtools for: gcc objcopy objdump ld
   Now using local cross tools /usr/bin/riscv64-linux-gnu-* on Ubuntu 24.04.
Need fix for riscv64-linux.elf-fold.h being 224 KB.
TODO: extend p_lx_elf.cpp  linker.cpp
TODO: implement nrv2d_d.S nrv2e_d.S lzma_d.S
TODO: testing  (using qemu-riscv64 and gdb-multiarch on Ubuntu 24.04)
