haikuports: LLVM17 references binaries in the wrong location

A build on buildmaster (32bit) for qt-creator revaeled this. cmake is looking for the binary in $binDir where the binaries are installed in $prefix/bin

CMake Error at /boot/system/lib/x86/cmake/llvm/LLVMExports.cmake:1151 (message):
 The imported target "llvm-tblgen" references the file

    "/boot/system/bin/x86/llvm-tblgen"

 but this file does not exist.  Possible reasons include:

 * The file was deleted, renamed, or moved to another location.

 * An install or uninstall procedure did not complete successfully.

 * The installation package was faulty and contained

    "/boot/system/lib/x86/cmake/llvm/LLVMExports.cmake"

 but not all the files it references.
