Weird behavior in glibc Makefiles, or: another example why you should never build software as root user (was: r5848 - in glibc-package/branches/eglibc-2.18/debian: . rules.d)

Hi!

Just seen this in the Debian glibc development repository:

Just for reference, this very much looks like the issue (as well as the
"solution") that I've described in
<http://news.gmane.org/find-root.php?message_id=%3C871uv99c59.fsf%40kepler.schwinge.homeip.net%3E>.
Someone ;-) should be doing something about this eventually.


Grüße,
 Thomas
