622677d4a1 libc: Implement exit, atexit, on_exit and cxa_exit on the user side

a bit of a security issue.

5c3d6bba6d libs: risc-v: Add R_RISCV_JAL support to arch_elf.c 
Summary:
- This commit adds R_RISCV_JAL support to arch_elf.c
- The code only checks the immediate value but does not relocate it
  because it is done by the compiler.

Impact:
- None

Testing:
- Tested with rv-virt:knsh64 (not merged yet)
