"MACHINE=qemux86-64 bitbake libsdl2-native" still fails with a similar
error:
| CMake Error at
/home/test/yocto-master/poky/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
This is triggered by the "pkg_search_module(UNWIND REQUIRED libunwind)"
line right above the one that is modified by this patch.
Any idea what is going on?

clang provides libunwind.h and cmake adds a check to
find libunwind when this header is detected, which was
not the case with automake. The check however is expecting
specific unwinder implementation which provides libunwind-generic
solib, this is not a standard library that all implementations
will provide, therefore make this check optional.
