Since introduced ? I did a grep in oe-core and meta-openembedded, it seems
that no ?

In oe-core:

$ grep 'COMPATIBLE_MACHINE.*qemux86' meta/recipes* -r
linux-yocto_4.4.bb:COMPATIBLE_MACHINE = 
"qemuarm|qemuarm64|qemux86|qemuppc|qemumips|qemumips64|qemux86-64"
linux-yocto-tiny_4.4.bb:COMPATIBLE_MACHINE = "(qemux86)"
linux-yocto-dev.bb:COMPATIBLE_MACHINE = 
"(qemuarm|qemux86|qemuppc|qemumips|qemumips64|qemux86-64)"
linux-yocto-tiny_4.1.bb:COMPATIBLE_MACHINE = "(qemux86)"
linux-yocto-rt_4.1.bb:COMPATIBLE_MACHINE = 
"(qemux86|qemux86-64|qemuarm|qemuppc|qemumips)"
linux-yocto-rt_4.4.bb:COMPATIBLE_MACHINE = 
"(qemux86|qemux86-64|qemuarm|qemuppc|qemumips)"
linux-yocto_4.1.bb:COMPATIBLE_MACHINE = 
"qemuarm|qemuarm64|qemux86|qemuppc|qemumips|qemumips64|qemux86-64"

In meta-openembedded:
vboxguestdrivers_4.3.30.bb:COMPATIBLE_MACHINE = "(qemux86|qemux86-64)"

We can see that the only one sets qemux86 but no set qemux86-64 is
linux-yocto-tiny:
COMPATIBLE_MACHINE = "(qemux86)"

And it really doesn't work with qemux86-64.
