Weak symbols do not work on all platforms. Luckily, making libqemustub
a static library gets exactly the same result without the need for weak
symbols: the definition from the QEMU object files will hide the stub.
You just need to remove __attribute__((weak)), and it should just work.
Otherwise, the patches look good to me. Luiz, do you have time to post
a pull request for v4, or do you want to pass HMP maintainership as well
to someone else?
Didn't look at the patch, but Patchew is catching this for cross build:
running command: /tmp/qemu-build/configure --prefix=/var/tmp/qemu-build-install
--cross-prefix=x86_64-w64-mingw32- --target-list=x86_64-softmmu,aarch64-softmmu
...
running command: make -j2 ...

As it turned out, this reaction occurs when using a weak symbol.
