This ensures that right sysroot is used during build, otherwise we see
warnings in build about using wrong sysroot and it fails explicitly with
clang

+Subject: [PATCH] cmake: Do not export CC into gir compiler
+
+this helps cross compilers where full compiler commandline defines the
+compiler rather than just CC variable, therefore let it use the default
+values from environment and not synthesize it from CMAKE_C_COMPILER just
+for this case.
