+Can't compile thunks on Arch Linux: undefined reference
+In Asahi Linux with a 4K page kernel, I installed the following dependencies with pacman:
+```
+git
+cmake
+ninja
+clang
+lld
+sdl2
+libepoxy
+squashfs-tools
+squashfuse
+```
+I then attempted to build FEX with cmake options `-DBUILD_THUNKS=True` and `-DBUILD_TESTS=False` (if I omit `-DBUILD_THUNKS=True`, the build succeeds) with the following error:
+```
+FAILED: Bin/thunkgen 
+: && /usr/bin/clang++ -flto=thin -fPIE -pie ThunkLibs/Generator/CMakeFiles/thunkgen.dir/main.cpp.o -o Bin/thunkgen  ThunkLibs/Generator/libthunkgenlib.a  -lclangTooling  /usr/lib/libcrypto.so && :
+/usr/bin/ld: cannot find -lclangTooling: No such file or directory
+```
+If I place a symlink to libclang-cpp.so in /usr/lib named libclangTooling.so, I get the following error:
+```
+FAILED: Bin/thunkgen
+: && /usr/bin/clang++ -flto=thin -fPIE -pie ThunkLibs/Generator/CMakeFiles/thunkgen.dir/main.cpp.o -o Bin/thunkgen  ThunkLibs/Generator/libthunkgenlib.a  -lclangTooling  /usr/lib/libcrypto.so && :

+/usr/bin/ld: /usr/lib/libLLVM-13.so: error adding symbols: DSO missing from command line
+clang-13: error: linker command failed with exit code 1 (use -v to see invocation)
+```
+
+Using lld with `-DENABLE_LLD=True` yields a similar error:
+```
