configure script reports stray, confusing "yes"

The configure script produced from configure.ac in Git HEAD produces puzzling output.

checking for strcasecmp... yes
checking for strlcpy... no
checking if run-time linking is supported... checking for library containing dlopen... -ldl
checking for dlfcn.h... (cached) yes
yes
checking if loadable i18n module support should be enabled... no
checking if loadable Xcursor library support should be enabled... yes
checking for sys/filio.h... no
checking for sys/select.h... yes

The text of Autoconf CHECKING and RESULT messages should not be nested.

Here's a patch.

Here's the result, having used autogen.sh to regenerate the configure script.
