description:
Via Jess Thrysoee, from Adrian Bunk: Fix libedit build on Linux/Alpha
Alpha is the only Linux architecture that has SIGINFO:
    https://sources.debian.org/src/manpages/5.10-1/man7/signal.7/#L522

But even on Alpha Ctrl-T is not supported, and therefore no VSTATUS:
    https://sources.debian.org/src/manpages/5.10-1/man3/termios.3/#L603-L608

For consistency check both signal existence and character existence
