Changelog:
https://wiki.qemu.org/ChangeLog/11.0

Note:
  - Support for all 32-bit host systems has been removed.
  - Support for microblazeel has been folded into the microblaze target

Qemu v11.0.0 drops 32-bit support for hosts, all qemu builds must now be
64-bit. Hosts running 64-bit qemu builds can still emulate 32-bit
targets.

Confusingly, the qemu package is also capable of being built and running
on buildroot hosts, and targets. In any case, qemu only supports running
on 64-bit hosts (which may be buildroot targets), so adjust
BR2_PACKAGE_QEMU_ARCH_SUPPORTS_TARGET to indicate no support for 32-bit
buildroot targets, and drop configs for architectures like BR2_arm that
are implicitly 32-bit only.

Separately, the qemu microblazeel target was removed with commit
46a25ae3f0e75e230c06e21435850b1cd1c44f07, as the microblaze (qemu)
target supports both endiannesses, so that's fixed up in the package
Makefile as well.
