Using only the first 16 bytes avoids the need to have separate entries
for i386 and i486, given that they are emulated by the same program

sh4 [2].
It's a bug in qemu-linux-user, which ignores CLONE_VFORK, turning vfork
into fork. This breaks the expected semantics of vfork (VM sharing and
blocking the child until exec).

Of course! I was confused by another patch I was working on which does
need such a conversion. :-/

This was tested by bootstrapping openSUSE Factory for RISC-V.

This is needed for new architectures like RISC-V which do not provide any
other rename-like syscall.

This is very much out of date, missing some important entries. Also,
TARGET_NR_syscalls needs to refer to TARGET_NR_*.

If your host doesn't have it, neither will the emulation.

A zero-length read still needs to do the usual checks, thus it may return
errors like EBADF.
