+Subject: [PATCH] CMakeLists.txt: allow to pick llvm-config from
+ usr/bin/crossscripts/
+
+ispc needs to invoke native llvm-config from target sysroot to list LLVM
+lib libraries. clang already provides crossscripts/llvm-config, which does
+the job.
+
+However, using LLVM_TOOLS_BINARY_DIR leads to wrong llvm-config being
+used. So remove it from search path for llvm-config.
+
+Upstream-Status: Inappropriate
