testing/tests: CLANG compiler-rt runtime test

Browse Source 
This patch adds a test case that
 1) Builds the complete LLVM and CLANG set of host tools
 2) Cross-compiles the compiler-rt runtime using CLANG
 3) Builds a cross-compiled application using CLANG and the libfuzzer
    compiler-rt library.
 4) Executes the fuzz application (part of the libfuzzer package) on
    target and checks expected output for a heap-buffer-overflow.

Note: The libfuzzer package is just a tutorial example of how to use
      the toolkit provided by llvm (Thus not adding it as a full
      Buildroot package).
