[Qemu-devel] [RISU PATCH] risu: Include <sys/user.h> on ppc64

[Peter Maydell <peter.maydell@linaro.org>]

To build the C parts of risu for ppc64le with recent glibc/kernel
headers, we need to include sys/user.h to avoid a compile error,
because sys/ucontext.h defines a struct which includes a pointer
to 'struct pt_regs' but does not provide a definition of that struct.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

I need this to be able to do the ppc64le cross-build on my
Ubuntu Bionic x86-64 system.
