Subject: qemuarm64 use lib64 as multilib

Hey guys,

I use poky as the test environment. work on kirkstone branch. test on qemuarm64.
I add this to local.conf
```
require conf/multilib.conf
MULTILIBS = "multilib:lib64"
DEFAULTTUNE = "armv7athf-neon"
DEFAULTTUNE:virtclass-multilib-lib64 = "armv8a"
DEFAULTTUNE:pn-linux-yocto = "armv8a"
```
I wish to use as this :
bitbake attr   : this would output 32bit file by default
bitbake lib64-attr: this output 64bit file

I know most people use lib64 as default, but I have to use lib32 as default.
I have to use a 64bit kernel (including all kernel module), and all the userspace as 32bit.

Now I bitbake yocto, I see this error.
```
ERROR: Nothing PROVIDES 'virtual/aarch64-poky-linux-binutils' (but /mnt/fileroot/hanliang.xiong/work/yocto-study/code/poky/meta/recipes-kernel/linux/linux-yocto_5.15.bb DEPENDS on or otherwise requires it). Close matches:
virtual/arm-poky-linux-gnueabi-binutils
virtual/arm-poky-linux-gnueabi-rust
virtual/lib64-aarch64-pokymllib64-linux-binutils
ERROR: Required build target 'linux-yocto' has no buildable providers.
Missing or unbuildable dependency chain was: ['linux-yocto', 'virtual/aarch64-poky-linux-binutils']
```
The DEPENDS is from kernel.bbclass, it expands to virtual/aarch64-poky-linux-binutils
But it seems no such provider.

Then how can I make it work?

Now I bitbake linux-yocto to compile kernel, I see this error.
