Subject: [PATCH] Correct library search path for OpenEmbedded Host
For OpenEmbedded Host, the gcc install path is
/usr/lib/x86_64-[distroname]-linux/[gcc-version].
So the library search path is not found with default triple
'x86_64-linux-gnu' for x86_64. Causing following error:
[snip]
compiler-rt-native/13.0.1-r0/recipe-sysroot-native/usr/bin/clang
-target x86_64-linux
-isystem/path/to/x86_64-linux/compiler-rt-native/13.0.1-r0/recipe-sysroot-native/usr/include
-O2 -pipe
/path/to/compiler-rt-native/13.0.1-r0/recipe-sysroot-native/usr/share/cmake-3.21/Modules/CMakeCCompilerABI.c`
