Vanilla u-boot-script is only built once per target arch. All normal specifics
are in the u-boot env. Or in /etc/default/u-boot-script that can be adjusted by
a machine-specific customization package. If you do the adjustment via
u-boot-script directly, you need to make that package in your overlay
machine-specific:

PN .= "-${MACHINE}"

See above if you are deviating from the default.

Again, please study jailhouse-images carefully. It contains working pattern and
- to my best knowledge - has no multiconfig issues.
