Could you please try to reproduce this problem with the latest release
of QEMU (version 2.6)? Thanks!

config/build problem due to libncursesw on Xenial
Status in QEMU:
it happened to me during a build of yocto/bitbake related cross tools.
the auto-configuration part titled "SDL probe" for qemu-2.2.0 i found
the configuration step failing for the compile_prog routine. actually
those test compile went fine but only the test linking failed.
this was due a reference of the sub-sub-...-included libcaca
referenced an initially not installed (hint: check for and report such
pre-requisites upfront - might be yocto related) and later on
installed by me component of name libncursesw seemingly in its dev
variant (i was installing
libncursesw5-dev_6.0+20160213-1ubuntu1_amd64.deb). tests on the
command line showed that adding the required paths and resources made
the test application link nicely.
a quick hack attempt for the config script resulted in those line:
sdl_libs="$sdl_libs -L/lib/x86_64-linux-gnu -lncursesw"
this allowed me to pass the configuration check nicely.
i am just seeing my full scale compile fail for the same reason multiple
times for linking. that all should be fixable the same way.
you might or might not have addressed this in newer versions of your
package. but you probably know that setups for embedded targets will
sometimes lack behind in their evolution until a sudden (well
prepared) some big jump in versions does happen. so i leave the hint
here for your reference - for the main reason of this very often
spotted message - raised by several main reasons according to public
web reports, but not this one until right here and now:
| ERROR: User requested feature sdl
| configure was not able to find it.
| Install SDL devel
By the way these lines already have to locations in the configure script
where the first indicates that pkg/sdl/sdl2-config application is not there
(=no SDL devel there)
whilst the second indicates that *-config is there but the test compile
failed (=devel is broken for some other reason).
This could/should see some improvement as well as this is the first hint on
what went wrong - and in the second case you definitely can give the user the
quite valueable hint for the log file with the results of the test compile.
