This adds an evil hack to persuade libstdc++, which tries to import __acrt_iob_func from a DLL.
This can only be solved cleanly by adding a GCC-compatible C++ standard library to our tree later.
This fixes the following compiler errors:
../sdk/lib/crt/stdio/stat64.c:7:13: error: inline function 'release_ioinfo' declared but never defined [-Werror]
inline void release_ioinfo(ioinfo *info);
^~~~~~~~~~~~~~

inline ioinfo* get_ioinfo(int fd);
