someone2639 c366e0122a Format the Repo (#3) 
* set build options

* remove COMPARE and MDOERN_* switches

* remove tools makefile

* AR patching is gone too since we want a fullly decomped version

* AR is modern

* remove cwd changes

* edit my own tool to fix compile errors

* compile files generated with my own tool instead of the originals

* inline modern_gcc makefile

* port mips toolchain detection logic

* add util.mk for find-command

* remove forced AR order and strip/mdebug removal commands

* add -mabi=32 to as flags

* formatting changes

* add clang format files

* formatting changes

* make libgultra CI work

* install mips gcc too

* add format check tools

* Add formatting to CI

* Add CI (#4)

* make libgultra CI work

* install mips gcc too

* remove make setup

* we don't use clang-tidy

* use 120 width for formatting

* a

* address clang-tidy messing up

* test

* align consecutive macros and declarations

* only align macros for now

* SpaceAfterCStyleCast: false

* format headers too

* remove cast space switch because its false by default

* pointers on left

* AlignConsecutiveBitFields: true

* install clang-format and clang-tidy on gh actions

* and clang-tools

* show diff in format check tool

* make CI work
