To repeat the same thing, just in a different coating: SeaBIOS is always built with an x86 compiler -- if you are on a non-x86 build host, then you either need a cross compiler to build it, or a working virtual machine that has (emulated) x86 architecture, and build SeaBIOS within it natively. Once you have it built, it is usually packaged up (for QEMU's purposes) as a "noarch" package -- installable on any kind of host. That's because you never run SeaBIOS natively on the host. On the host, the SeaBIOS binaries are only *data*. QEMU loads the SeaBIOS binary (+ the SeaVGABIOS oprom) from the host data files, if it emulates or virtualizes an x86 target. SeaBIOS runs within the guest. Note, if you don't build qemu-system-i386 / qemu-system-x86_64 from QEMU, only qemu-system-arm / qemu-system-aarch64, then you won't need SeaBIOS at all. The packaging of QEMU might not reflect this on your distro, but that's a packaging problem then.
