"make test" comments

[David E. Weekly]

Just as a heads-up, "make test" in 2.5.5 release did not, on my system, use
the rsync in the build directory. Instead, it just exec's "rsync" -- since
"." is not in my path, it uses the system rsync. This could quietly give a
false sense of confidence to folks working on the code if the prior version
installed is nice & stable.

I don't think my setup (vanilla x86 RH7.1) is very fancy or strange.

Am I doing something wrong, or is there a problem with the "make test"
target?
