D:\code\incubator-nuttx\libs\libc\stdlib\lib_strtod.c: error C2124: divide or mod by zero

Windows MSVC restrictions, MSVC doesn't allow division through a
zero literal, but allows it through non-const variable set to zero

2ce12617a1 libs: spawn: Add forkaround for posix_spawn_file_actions_adddup2()
Summary:
- I noticed that adb shell failed when sh is spawned.
- Finally, I found that an error happened when executing dup2() action
  if the file descriptor has the O_CLOEXEC option.
- This commit fixes this issue by dropping the option in the API.

Impact:
- posix_spawn_file_actions_adddup2() only

Testing:
- adbd with sabre-6quad:netnsh (will be merged later)

bf91047f33 libc: Fix getrandom() bug: Didn't propagate read error
* libs/libc/misc/lib_getrandom.c, in function getrandom():
  We were assigning the return value of _NX_READ() to nbytes, a
  variable of the unsigned type size_t. Note that _NX_READ() resolves
  to either read() or nx_read(), both of which return the signed type
  ssize_t to indicate either the number of bytes read successfully
  (>= 0) or an error (< 0). Then we were testing for a negative
  size_t value, a condition that can never occur. The end result is
  that if an error occured in _NX_READ(), it would never be detected
  and getrandom() would return some large positive value. This bug is
  corrected by assigning the return value of _NX_READ() to a new local
  variable, ret, of size ssize_t.

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)

The jump instruction relocation had an assert that tests for jumps with
an offset of 0. This makes it so that a while(1); statement causes an
assert because the jump instruction points to the same address, which
is perfectly legal.

Addend was not handled correctly in several reloc types.

I use likes to add them.
