Hi Eric.
I noticed that (sometimes?) the lseek check prints a "broken
pipe" message in the middle of "configure" output, e.g.
checking whether lseek detects pipes... ../configure: line 30326: echo:
write error: Broken pipe
as reported here under step 19:

I think that we should redirect stderr to /dev/null for that
test.
May I push the following to gnulib?
Thanks,
Ben.

Avoid "broken pipe" message from lseek test.
* m4/lseek.m4: Redirect stderr to /dev/null when writing to a pipe
that will not be read from.
