1. elf2flt: add riscv 64-bits support …

   Add support for riscv 64bits ISA by defining the relocation types
   R_RISCV_32_PCREL, R_RISCV_ADD32, R_RISCV_SUB32, R_RISCV_32 and
   R_RISCV_64. riscv64 support also needs the __global_pointer$ symbol to
   be defined right after the relocation tables in the data section. To
   define this symbol, the "RISCV_GP" line prefix is added. The "RISCV_GP"
   string is removed if the target CPU type is riscv64 and the definition
   line is dropped for other CPU types.
   
   With these changes, buildroot and busybox build and run on riscv NOMMU
   systems with Linux kernel including patch 6045ab5fea4c
   ("binfmt_flat: do not stop relocating GOT entries prematurely on riscv")
   fixing the binfmt_flat loader. Tested on QEMU and Canaan Kendryte K210
   boards.
   
   This patch is based on earlier work by Christoph Hellwig <[email protected]>.
