Resolve Build Errors with ARM GCC 10.3.1 20210621

[lain-core]

Resolves #37

Description

When compiling master with arm-none-eabi-gcc version 10.3.1 20210621 (release) via WSL2 Ubuntu an error is raised:

/usr/lib/gcc/arm-none-eabi/10.3.1/cc1 -quiet <flags> -o build/modern/src/pokemon_summary_screen.o src/pokemon_summary_screen.c
src/pokemon_summary_screen.c: In function 'BufferIvOrEvStats':
src/pokemon_summary_screen.c:3584:9: error: a label can only be part of a statement and a declaration is not a statement
 3584 |         const s8 *natureMod = gNatureStatTable[
      |         ^~~~~
make: *** [Makefile:340: build/modern/src/pokemon_summary_screen.o] Error 1
make: *** Deleting file 'build/modern/src/pokemon_summary_screen.o'

This is caused by the case statement default: immediately being followed by a declaration of a const s8 *, and is thus resolvable by simply placing a blank statement prior to evaluating the default switch case.

If I'm not mistaken, this error only occurs when not compiling with "make modern". Other errors may come up during compiling if "make modern" is not used, which is what I've been using since I started developing this hackrom.
