Debug build now takes .alf as input instead of .dol (#2360)

* Fix debug build

* Debug build now takes .alf as input instead of .dol

I had to manually remove the following line from symbols.txt for DTK to work:
```
.data = .sbss:0x8074C97C; // type:object size:0x4 scope:local data:byte
```
After that it built OK, and DTK automatically modified all other lines in symbols.txt.

* Fix pragma in header messing up debug optimization level
