test-getcwd-lgpl fails on FreeBSD 8.1

[Matthias Bolte]

I found this while testing current libvirt git on FreeBSD 8.1 32bit.

When running gmake check in the libvirt source tree then ASSERT
(getcwd (NULL, i) == NULL) in test-getcwd-lgpl.c in line 74 fails on
the first iteration of the for loop. When runnig in gdb
./gnulib/tests/test-getcwd-lgpl in the libvirt source tree then the
same ASSERT fails. Sometimes ASSERT (chdir (pwd1) == 0) in
test-getcwd-lgpl.c in line 51 fails too, but I'm not able to reproduce
this one reliably.

This also happens with current gnulib git head.
