Description

On arch (and maybe some other rolling release distros) the current version of gcc is 12.1, and there's a bug ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105523 ) which results in a bunch of error: array subscript 0 is outside array bounds of ... here and there. The problem is solved in the main qmk_firmware repo with 3 new lines of code in platforms/avr/platform.mk.

Basically, it'd be geat if you reflect the changes made with the following pull request:

• Workaround for recent -Werror=array-bounds AVR issues qmk/qmk_firmware#17136

And for now those who have the same problem can just go to the files section and copy-paste those 3 lines in the corresponding file.

Should be resolved now
