Subject: [PATCH] configure: Fix typo in libXmu check.

As the literal string "wm_cv_xext_xmu" will never be equal to "xno",
we always ran the code that was supposed to run when the variable
$wm_cv_xext_xmu was not equal to "no".  In particular, if libXmu
was not found, then we proceeded as if it had been found.
