[PATCH v2] linux/mips: handle wait status 0x7f specially for WIFSIGNALED and WIFSTOPPED

[Florian Weimer]

* Xi Ruoyao:

> MIPS Linux has SIGRTMAX=127, thus the wait status 0x7f means the program
> is terminated by SIGRTMAX, not stopped.
>
> This cannot happen on other ports so make a special version of
> waitstatus.h for MIPS to avoid adding redundant calculation to others.
> I cannot find a way to use status only once in the expression, so use
> inline functions instead of macros to avoid double-evaluating status.

This version looks okay to me.

I'm going to push this for you.

You should probably apply for push access for yourself.  However, I
can't approve that myself.

Thanks,
