Subject: QEMU 4 fails to build for x86_64-linux
Date: Wed, 31 Jul 2019 16:03:34 -0400

While testing the upgrade of our QEMU package to 4.0.0 or 4.1.0-rc3 on
x86_64-linux, the build fails when the header 'gnu/stubs-32.h' can't be
found:

------

------

And of course, this header is not installed by glibc when it is built
for 64-bit systems.

The header in question, 'stubs.h', looks like this:

------
#if !defined __x86_64__
# include <gnu/stubs-32.h>
#endif
#if defined __x86_64__ && defined __LP64__
# include <gnu/stubs-64.h>
#endif
#if defined __x86_64__ && defined __ILP32__
# include <gnu/stubs-x32.h>
#endif
------

When I build for i686-linux, it works as expected.

Any advice? I'm not really sure what's going on here.
