Some system header files on AIX include inttypes.h without
defining __STDC_FORMAT_MACROS and therefore the printf format
specifier macro (for eg. PRId64) doesn't get defined as they
are guarded with __STDC_FORMAT_MACROS macro on AIX.
This error showed up recently when the format specifier was used in
wasm-interpreter.cc, where a AIX system header file is included
which also includes inttypes.h without defining __STDC_FORMAT_MACROS.
