Subject: [PATCH] RIOT: Provide PRIx64 if needed

Not all RIOT platforms provide a PRIx64 or even 64-bit printing.

As the debug routines that actually use this definition are unlikely to
be used with RIOT, providing a definition that builds (and, depending on
platform support, may or may not produce correct output) is a suitable
fix.
