Hi
         I have faced a problem about the MULTILIB in poky , that is I enable the MULTILIB in the local.conf like this:
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"
IMAGE_INSTALL = "lib32-connman"

And I have my own layer name meta-rtos. I set the layer.conf like this:
# We have a conf and classes directory, add to BBPATH
BBPATH := "${BBPATH}:${LAYERDIR}"

# We have a packages directory, add to BBFILES
BBFILES := "${BBFILES} ${LAYERDIR}/recipes-*/*/*.bb \
                               ${LAYERDIR}/recipes-*/*/*.bbappend"

BBFILE_COLLECTIONS += "rtos"
BBFILE_PATTERN_rtos := "^${LAYERDIR}/"
BBFILE_PRIORITY_rtos = "8"

         The problem is that I compile a package "bitbake lib32-ncurses" , poky find the sourcecode from meta not from meta-rtos , because the version in meta-rtos is 5.7 the version in meta is 5.9 .
         So I want to know why the problem occur? Why the priority have no effect in MULTILIB ? Is there any problem of my configure file ?

It seems to me this is a bug - you can see it even with native/nativesdk 
versions of ncurses, so I suspect it applies to anything using BBCLASSEXTEND. 
I've filed a bug for this:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=2933

As a workaround you should be able to do the following:

PREFERRED_VERSION_lib32-ncurses = "5.7"

Cheers,
Paul
