[PATCH 0/4] Fix the build failure when creating a multilib wic

[Kevin Hao <kexin.hao@windriver.com>]

We have observed the following build failure when building lib32-core-image-minimal
for a qemux86-64 machine.
    DEBUG: | ERROR: Couldn't find correct bootimg_dir, exiting
    | ERROR: Couldn't find correct bootimg_dir, exiting
    DEBUG: | 

This patch series tries to fix this issue. You can use the following
steps to reproduce this issue:
 1. source .../git/poky/oe-init-build-env and set the MACHINE to
"qemux86-64"

 2. Add the following to conf/local.conf:
    IMAGE_FSTYPES = "wic"
    
    MULTILIBS = "multilib:lib32"
    require conf/multilib.conf
    DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

 3. bitbake lib32-core-image-minimal

  wic: bootimg-pcbios: Drop the unnecessary reference of STAGING_DATADIR
  wic: isoimage-isohybrid: Drop the unnecessary reference of
    STAGING_DATADIR
  bitbake.conf: Introduce variables used to access the other recipe
    specific sysroot directory in multilib case
  wic: Set the right bootimg_dir when building a multilib image
