== DETAILS
Updates to the newlib library bundled with DevKitPro have caused
incorrect behavior in `cpu_features_get_time_usec()`. Specifically,
it defines `_POSIX_MONTONIC_CLOCK` which results in calling newlib's
time functions which are.. buggy, at least on Wii U.
By moving the WIIU case higher up, we end up calling the actual
Wii U time library routines, and get nice snappy animations as a
result.
== TESTING
I tested this locally on my wiiu and confirmed resolved menu sluggishness.
