FWIW I believe configuring buildroot with i486 processor builds you a
toolchain for an i486.  A i486 toolchain seems to work well for me on a
vortex86dx.

I tend to configure buildroot to pick up a kernel config:

 make menuconfig

Select "Kernel" then "Linux Kernel".
Select "Kernel configuration (Using a defconfig)" and select "Using a custom
config file".
Select "() Configuration file path" and enter the path to your desired
kernel config.

Others with a better understanding can tell you if what you are experiencing
might be considered a bug...

X-Linux provided kernel configs changed (quite considerably) between v5.6
and v5.7 as to quite what processor / processor features they declare the
vortex86dx to have, the same may be true for the vortex86mx.  Perhaps you
can gain some understanding from a diff of these?

Will
