package/kvm-unit-tests: new package The unit tests are tiny guest operating systems that generally execute only tens of lines of C and assembler test code in order to obtain its PASS/FAIL result. Unit tests provide KVM and virt hardware functional testing by targeting the features through minimal implementations of their use per the hardware specification. The simplicity of unit tests make them easy to verify they are correct, easy to maintain, and easy to use in timing measurements. Unit tests are also often used for quick and dirty bug reproducers. The reproducers may then be kept as regression tests. It's strongly encouraged that patches implementing new KVM features are submitted with accompanying unit tests. Signed-off-by: Cyril Bur <cyrilbur@gmail.com> [Thomas: - order architecture dependencies in Config.in alphabetically. - rewrap Config.in help text, lines were too long - add an empty line between the package description and the upstream project URL in the Config.in help text - don't make KVM_UNIT_TESTS_ARCH default to $(ARCH). This was not correct for i386 for example. Instead, just handle the few architectures that the package supports. - remove useless double quotes in variable definitions. - remove --prefix="$(TARGET_DIR)" from CONF_OPTS. It was installing everything in /share/ and not /usr/share/, and setting the prefix to TARGET_DIR at configure time is not good.

kvm-unit-tests: Fix x86_64 to use host compiler kvm-unit-tests requires a multilib compiler for x86_64 as it compiles 32bit boot code. This patch uses the BR2_HOSTARCH_NEEDS_IA32_COMPILER option to enforce this and avoids using TARGET_CROSS for x86_64 targets and uses the host 32bit (and 64bit) capable compiler.

# For all architectures but x86-64, we use the target
# compiler. However, for x86-64, we use the host compiler, as
# kvm-unit-tests builds 32 bit code, which Buildroot toolchains for
# x86-64 cannot do.

package/kvm-unit-tests: really fix build on Arch Linux x86_64 On x86_64, we use the host compiler instead of the target compiler to build kvm-unit-tests, because it is built with -m32 and our target compiler doesn't support that. However, the compiler on Arch Linux is broken: it *always* builds with -fstack-protector, even when -ffreestanding is passed. However, when -fnostdlib is passed at link time (which is normally the case when building with -ffreestanding), it is not linked with the stack-protector library. This leads to a link time error: /usr/bin/ld: x86/realmode.o: in function `print_serial_u32': .../x86/realmode.c:104: undefined reference to `__stack_chk_fail' Since the entire package is built with -ffreestanding, it doesn't support stack-protector at all. Therefore, simply pass -fno-stack-protector explicitly on x86_64 to work around the bug in Arch Linux. Commit c0ffd16e4 tried to do this, but got the condition wrong: -fno-stack-protector was passed in all cases *except* for x86_64. This commit fixes that, by inverting the condition and moving the --cross-prefix part to the else branch.
