Can't run `make universe` on universe11a.freebsd.org and ref11-amd64.freebsd.org (anymore); [shell] globbing is broken [there]

Hi,
	I’ve been trying to run `make tinderbox` on universe11a.freebsd.org for the past couple of days and it’s not working because of this error:

$ svn diff Makefile

	This seems to workaround the issue, but it definitely doesn’t solve the underlying cause:

	Oddly enough, this is only an issue with /bin/sh on universe11a (hat tip to bdrewery for the suggestion):

ref11-amd64.freebsd.org appears to be affected as well:

$ (cd sys/amd64/conf && echo [A-Z0-9]*[A-Z0-9])

It looks like a libc problem though, because I’ve run into this issue with both /bin/sh and bash (my default login shell). I’m not sure why this isn’t reproing on my VM (yet).

This doesn’t repro in universe10a.freebsd.org (another jail on the same machine I think…).

It was working yesterday on ref11-amd64.freebsd.org before the system was upgraded (it was running October sources), and wasn’t working on universe11a.freebsd.org yesterday (it was running December sources yesterday).

Thanks!
