QEMU provides a single system emulator that supports both powerpc64
and powerpc64le with a target called 'ppc64-softmmu', but it provides
a different usermode emulator for each one (with targets
'ppc64le-linux-user' and 'ppc64-linux-user').
Due to this asymmetry it is not possible to support both cases with
the single arch value used in the package file. This patch introduces
an additional value into the package configuration,
HOST_QEMU_SYS_ARCH, so that both cases can be supported.

Like for cyclictest (rt-test)[1], linux-user/syscall.c use the

So, disable Qemu user-land emulation for musl toolchains.

Similar to what was done in commit
524b6b8559 for the host variant, this
commit fixes the build of qemu's host variant. Qemu expects that the
cpp it is passed behave like cc: it passes the -c option, which is not
allowed by cpp, but is allowed for cc.
Fix that by overriding CPP when calling configure.

Fix that by overriding CPP when calling configure.
Note: the target variant of Qemu does not build the affected parts (the
PC-BIOS images). This is another problem that should be fixed separately.

This commit adds support for building the system emulation mode in
host-qemu. To do so, it adds the BR2_PACKAGE_HOST_QEMU_SYSTEM_MODE and
BR2_PACKAGE_HOST_QEMU_LINUX_USER_MODE sub-options, making sure that the
latter is selected if the former is not enabled. This ensures that at
least one is enabled *and* that existing configurations continue to
build the user-land emulation (which was the only one we supported until
now).
The list of architectures supported by the system emulation mode is the
same as the one for the user-space emulation mode (as far as the
existing list is concerned), so we simply drop the comment about this
dependency list being related to the user-space emulation only.

- Remove the unneeded BR2_PACKAGE_HOST_QEMU_HAS_EMULS option.
- Remove the SDL related option, we really on the system to provide
SDL.
- Remove the BR2_PACKAGE_HOST_QEMU_DEBUG and
BR2_PACKAGE_HOST_QEMU_STRIP_BINARY options, since they are not really
useful.
- Remove HOST_QEMU_SITE and HOST_QEMU_SOURCE definitions, since they
are automatically derived from QEMU_SITE and QEMU_SOURCE anyway.

The Linux kernel doesn't even support i386 anymore, there is no NPTL
support for i386 and uClibc-ng only supports NPTL on x86, so there is
essentially no usable thread implementation. Most likely glibc and
musl also don't support i386 either. So it's time to remove the

The QEMU configure script incorrectly assumes SSP is supported by the
toolchain in some cases where the compiler accepts -fstack-protector*
flags but the C library does not provide the necessary __stack_chk_*()
functions.
Even though a full compile and link test is performed by the script,
this is done with a code fragment which does not actually meet any of
the conditions required to cause the compiler to emit canary code when
the -fstack-protector-strong variant is used. As no compile or link
failure occurs in this case, a false positive is generated and a
subsequent error is seen when the probe for pthreads is performed.
The fix consists in patching the configure script to use a more
appropriate test program for the SSP support checks.

Qemu doesn't understand sh4a and sh4aeb as separate architectures, it
only knows about sh4 and sh4eb. However, it does support sh4a, since
it emulates the SH7785 CPU which is a SH4A.
Therefore, with this commit, sh4a/sh4aeb are translated as sh4/sh4eb
for Qemu.

commit f7add51c39 (qemu: add host/target Linux version check) added a
version check between the host kernel version and the version of kernel
headers used by the toolchain, but the logic would fail unless BOTH major
and minor versions were >=, which isn't true for E.G. host kernel = 3.2 and
toolchain 2.6.x.
Instead calculate a single version number (as major << 8 + minor) and
compare that.

Raise an error if the host is using an older kernel than the target.
Since qemu-user passes emulated system calls to the host kernel,
this prevents usage of qemu-user in situations where those system
calls will fail.
This is based on an original patch from Frank Hunleth
<fhunleth@troodon-software.com>, but completely rewritten in a
different way:
* Instead of using shell based testing, we use pure make tests, which
allows to detect the problem not when host-qemu starts to build,
but at the very beginning of the entire Buildroot build.
* Instead of looking at $(STAGING_DIR)/usr/include/linux/version.h
(which requires having a dependency on the 'toolchain' package,
which is a bit unusual for a host package), we use the
BR2_TOOLCHAIN_HEADERS_AT_LEAST Config.in option which tells us the
version of the kernel headers used in the toolchain.
