[bug#68746] system information in test-suite.log?

[Karl Berry]

I had the idea that it would be helpful to put basic system information
into test-suite.log, as shown below. Although most people reporting bugs
are good about including their system info, not everyone does. And
details are good.

I figured the output of uname -a and /etc/os-release || /etc/issue would
be enough to go on. That certainly won't cover all systems, but if
nothing shows up, we'll be no worse off. I eliminated the local host
name from uname -a for privacy, just in case. I don't think anything
else in there is at all problematic.

I don't think anything anything parses test-suite.log with such rigidity
that adding some lines near the beginning will cause problems, and
automake's own make check didn't care, but I guess I don't know for sure.

If anyone sees a problem with this, let me know. --thanks, karl.
