Are you trying to substitute a gcc cross-compiler with a native clang compiler?

Have you tried to use gcc's -isysroot that point to the tooolchain
installation prefix?

There's as well a few clang-static-analyser and/or scan-build options
such as --analyzer-target --triplet, ...
I don't have the recipe at hand, but AFAIR you need to tell clang that
this is cross compiled.
