How about checking against $  ?

Actually, this is not really a problem. This directory change is pretty much
the last thing configure does and it not even gives a fatal error message. It's
more like a warning and installation works anyways.

I really think the problem is AC_SHELL_QUOTIFY. Using this, too much
quotification is inserted into variables. At the next unquoted (=incorrect) use
this goes away again, but quoted (=correct) use does not work any more.
