Yes. It just does not install anything useful:

$ cat build/qemu-7.2.0/.files-list.txt
qemu,./usr/share/qemu/keymaps/sl
qemu,./usr/share/qemu/keymaps/sv
qemu,./usr/include/qemu-plugin.h

qemu,./usr/share/qemu/keymaps/th
qemu,./usr/share/qemu/trace-events-all
qemu,./usr/share/qemu/keymaps/tr

The keymaps should not be installed if no qemu-system is built. I
already sent a patch upstream attempting to fix the problem but the
problem is still there:

https://lists.gnu.org/archive/html/qemu-devel/2023-01/msg00084.html

I also have a patch to install trace-events-all only if necessary.
Unfortunately, making these changes happen in qemu takes a long time.
