It is very hard to explain why this public interface class was defined
in an anonymous namespace inside a header file.

When compiling with -DCMAKE_BUILD_TYPE=Debug, GCC would (correctly) fail to
compile intrinsics in stb and host1x due to lack of optimizations.

Sadly, the compilation error given is bogus and Clang completing the builds
without issues does raise some eyebrows.

Therefore, force optimizations for the offending files under GCC when
creating Debug builds.
