[PATCH V3 0/1] multilib.bbclass/package_manager.py: fix <multilib>-meta-toolchain build failure

[Hongxu Jia <hongxu.jia@windriver.com>]

Changed in V3:
Comparisons to singletons like None should always be done 'is not'

Changed in V2: 
V1 caused build failure of meta-toolchain, in order to avoid it, we
should use DEFAULTTUNE_virtclass-multilib-lib32 first, if it is not 
available, and try to use DEFAULTTUNE_ML_<multilib> 

Test steps:

1. env
vim local.conf
...
MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS ?= "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 ?= "x86"
...

2. build lib32-meta-toolchain success
$ bitbake lib32-meta-toolchain

3. build meta-toolchain success
$ bitbake meta-toolchain
