In current code, __NR_msgrcv and__NR_semtimedop are supposed to be
defined if __NR_msgsnd is defined.
But linux headers 5.2-rc1 for MIPS define __NR_msgsnd without defining
__NR_semtimedop and it breaks the QEMU build.
__NR_semtimedop is defined in asm-mips/unistd_n64.h and asm-mips/unistd_n32.h
but not in asm-mips/unistd_o32.h.
Commit d9cb433615 ("linux headers: update against Linux 5.2-rc1") has
updated asm-mips/unistd_o32.h and added __NR_msgsnd but not __NR_semtimedop.
It introduces __NR_semtimedop_time64 instead.
This patch fixes the problem by checking for each __NR_XXX symbol
before defining the corresponding syscall.
