+"accel/tcg: demacro cputlb" break qemu-system-x86_64 on 32-bit x86 host
+
+As described in https://lists.gnu.org/archive/html/qemu-devel//2019-05/msg07362.html I run into TCG regression in qemu-git.
+
+Unfortunately, fix from bug https://bugs.launchpad.net/qemu/+bug/1830872 seems to be nonn-effective for my case.
+
+For reproduction (on 32-bit x86 host, in my case Slackware with gcc 5.5.0):
+
+./configure --target-list=x86_64-softmmu --disable-werror --enable-debug-tcg
+
+make (-j5 in my case)
+
+try to boot any 64-bit kernel:
+
+x86_64-softmmu/qemu-system-x86_64 -kernel /boot/bzImage-4.12.0-x64 -accel tcg
+
+result is - qemu appear to hang right after "Booting the kernel" line. Decompression (xz) was ok.
+
+Tested with qemu-git commit  e2a58ff493a2e00db3e963c1839c5374500110f2 
+
+32-bit OS can be booted fine, and -enable-kvm also allow 64 bit kernel/os to boot.
