Yes, make always cd's to the obj directory if there is one,
so that the current directory is always the object directory.

The test used to work when there was no obj directory in
/usr/src, so make didn't cd to it, but now that the object
tree exists independently of symlinks to it, there is no way
to avoid having a (virtual) obj directory in /usr/src.
