The forthstrap Forth interpreter segfaults on aarch64 builders due to pointer truncation in cell2pointer() — mmap returns addresses above 4 GiB that do not fit in a 32-bit cell. This is a known upstream bug with no fix (openbios/openbios#18, #25). Add ExclusiveArch: x86_64 so Koji only schedules the build on x86_64 builders where the address space layout avoids the crash. The output RPMs remain noarch (firmware blobs for ppc/sparc). Build verified locally; firmware ELFs inspected in mock.

Pull request overview
Adds an Azure Linux component overlay for openbios to restrict builds to x86_64, avoiding a known upstream forthstrap segfault on aarch64 builders while keeping the resulting firmware RPMs noarch.
Changes:
- Introduce
base/comps/openbios/openbios.comp.tomlwith an overlay addingExclusiveArch: x86_64. - Remove the inline
[components.openbios]entry frombase/comps/components.tomlto avoid duplicate component definitions.
