Drop LLVM

[sonnyp]

Fixes #611

I tried to make mold work with gcc with -C link-arg=-fuse-ld=mold -C link-arg=-B=/usr/lib/sdk/rust-stable/ but it resulted in note: collect2: fatal error: cannot find 'ld'

Anyway, I can't see a difference with our without Mold - could it be the gnu linker is substantially faster now?

@Hofer-Julian wdyt?

Mold stopped working?

I can't see a difference with our without Mold

You mostly notice see the difference with incremental builds.

Not that I would know

No i meant that I tried to make mold work with gcc

I really don't but I must be missing something. How can I trigger it? I'll do some benchmarks with/without Mold

On my machine, I get the following results:
1.5 seconds for "Web View" with Mold
4 seconds for "Web View" with gold

A big difference in relative numbers, but both compile times are very acceptable.
If that makes your lives easier, I am fine with dropping Mold and LLVM.
