Image directiory is populated as expected (has lib, usr/include etc with
expected files).  Build is failing on populate_sysroot:

CalledProcessError: Command 'tar -cf - -C
/home/build/poky-edison-6.0/build/tmp/work/i686-linux/libmylib-native-2.1.4-r0/sysroot-destdir///home/build/poky-edison-6.0/build/tmp/sysroots/i686-linux
-ps . | tar -xf - -C
/home/build/poky-edison-6.0/build/tmp/sysroots/i686-linux' returned
non-zero exit status 2 with output tar:
/home/build/poky-edison-6.0/build/tmp/work/i686-linux/libmylib-native-2.1.4-r0/sysroot-destdir///home/build/poky-edison-6.0/build/tmp/sysroots/i686-linux:
Cannot chdir: No such file or directory
tar: Error is not recoverable: exiting now

The failure is obviously due to sysroot-destdir being empty.  The
question is why this directory is populated for libmylib but not for
libmylib-native ... they're built from the same recipe.
