By examining negative scenarios of these syscalls for Mips, it was established that ENOMSG does not have the same value accross all platforms, but it is nevertheless not included for conversion in the correspondant conversion table defined in linux-user/syscall.c. This is certainly a bug, since it leads to the incorrect emulation of msgrcv() and msgsnd() for scenarios involving ENOMSG. This patch fixes this by extending the conversion table to include ENOMSG. Also, LTP test msgrcv04 will be fixed for some platforms.
