+CMake: support building with musl libc
+
+Instead of using macros like GLIBC we can use the CMake build
+systems internal functions to check if some header or functions are
+present on the running system's libc.
+
+Add ./build_files/cmake/have_features.cmake to add checks for
+platform features which can be used to set defines for source
+files that require them.
+
