Subject: [PATCH] Disable libunwind in native OE builds by not looking for
 libunwind

This is a workaround for this build error:

| -- Checking for one of the modules 'libunwind'
| CMake Error at [...]/build/tmp/work/x86_64-linux/libsdl2-native/2.0.20-r0/recipe-sysroot-native/usr/share/cmake-3.22/Modules/FindPkgConfig.cmake:890 (message):
|   None of the required 'libunwind' found
| Call Stack (most recent call first):
|   CMakeLists.txt:1367 (pkg_search_module)

By not looking for the libunwind header, the rest of the libunwind
specific bits in the CMake build script are disabled.

Upstream-Status: Inappropriate [OE specific]
