It looks to me like the AS_IF part in upstream configure.ac is buggy:
https://git.gnome.org/browse/mutter/tree/configure.ac#n264

There should likely be a final [have_wayland=no] to fall back on if
all tests fails, or atleast that's how I read:
https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Common-Shell-Constructs.html

I don't find autotools or non-linux very fun to deal with myself
so would appreciate if someone who does would provide upstream
with the portability assistance.

As a last resort I guess we could just work around this by explicitly
passing --disable-wayland on non-linux from debian/rules instead of
relying on "auto" doing the right thing.
