Some systems have a version of /bin/sh whose builtin echo doesn't
support the -n option used in test/test.sh. /bin/echo, however,
usually does. This patch makes us use /bin/echo for echo -n whenever
it is present.
Also, our use of echo -n really only made sense when suppressing all
test output. Since test output isn't suppressed when logging to a
file, this pach makes us stop using echo -n when logging to a file.
By default, the test.sh script still suppresses the output of all the
tests it invokes. Now, however, you can have that output written to
a file specified in the TEST_OUTPUT_FILE shell variable.
Remove rtsig method, as discussed in July. It hasn't compiled for quite a while, and nobody has seemed to miss it much. Please let us know if this was a bad call. [Tracker issue 1826539].
