LibC: Use our implementation of `crti.o` and `crtn.o` We have had these for quite a while, but we didn't compile them, and used GCC's version instead. Clang does not come with these, so we have to provide our own implementation. Our implementation follows what `musl` and `FreeBSD` do, so this should work fine, even if documentation can hardly be found for them. 2021-07-12 21:37:38 +03:00			`/*`
