I can understand the confusion. In this case I am a Linux distribution
developer and this is the exact binary I want to debug and use.
Currently I don't even know if the QEMU or the Xen package is to blame.

The binary was built as a part of an RPM package, so the 'configure'
line used is not simple:

./configure '--extra-cflags=-O2 -fwrapv -pipe -Wformat \
  -Werror=format-security -gdwarf-4 -fno-debug-types-section \
  -fvar-tracking-assignments -g2 -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector \
  --param=ssp-buffer-size=4 -fPIC -march=x86-64 -gdwarf-4 \
  -fno-debug-types-section -fvar-tracking-assignments -g2 \
  -I/usr/include/ncurses' '--extra-ldflags=-Wl,--as-needed \
  -Wl,--no-copy-dt-needed-entries -Wl,-z,relro -Wl,-z,combreloc ' \
  '--prefix=/usr' '--sysconfdir=/etc' '--cc=x86_64-pld-linux-gcc' \
  '--host-cc=x86_64-pld-linux-gcc' --disable-strip --enable-attr \
  --disable-bluez --disable-brlapi --enable-cap-ng --enable-curl \
  --enable-curses --enable-docs --enable-fdt --disable-glusterfs \
  --disable-libiscsi --disable-glx --disable-rbd --disable-rdma \

  --enable-vnc-tls --enable-kvm --enable-xen '--audio-drv-list=alsa' \
  '--interp-prefix=/usr/lib64/qemu/lib-%M' --disable-gtk
