Well yes, I use buildroot running on bigiron Linux machines to
cross-compile for customer platforms. But you should be able to set it
to run on a Pi for a Pi. I haven't tried it but it should be just a case
of setting the cross-compiler to be the installed gcc on the Pi.

It takes a while on a 48core Xeon with 256G of ram so I'm not sure how
that will work out even on a Pi4. You'd certainly want something better
than an SDcard for storage!
