Comment # 6 on bug 1175266 from David Disseldorp

I've updated the upstream bug...

>From the glibc 2.32 release notes:

    The functions sigabbrev_np and sigdescr_np have been added. The
    sigabbrev_np returns the abbreviated signal name (e.g. "HUP" for SIGHUP)
    while sigdescr_np returns a string describing the signal number (e.g
    "Hangup" for SIGHUP). Different than strsignal, sigdescr_np does not
    attempt to translate the return description, both functions return
    NULL for an invalid signal number.

    They should be used instead of sys_siglist or sys_sigabbrev and they
    are both thread and async-signal safe. These functions are GNU extensions.

I'll propose a patch to use sigabbrev_np() if available.
