Hi, all. Has anyone had any success compiling a Musl-linked 
druntime and phobos? I haven't had any luck so far. I'm running 
Linux Mint x64.

Somewhat related - using `-target=x86_64-linux-musl` with dmd 
master doesn't even set the version `CRuntime_Musl`. I asked 
about this in the Discord, and I was told by Horo:

 dmd 2.096 worked well for me. Same for gdc, haven't tried ldc. 
 There is/was a bug that was introduced recently in druntime 
 that broke musl but the older versions should work fine

2.096 doesn't have the `-target` option, and 2.097.0-2.098.0 
don't even build properly for me. Using LDC to build works of 
course, but only with `-betterC` (i.e. no druntime/phobos).

Hi!
Thinks should mostly work. There is some issues with stack 
traces, but I don't remember the details. Check what Alpine Linux 
is doing: 
https://gitlab.alpinelinux.org/alpine/aports/-/tree/master/community/dmd

Note that the `target` should not be required: 
https://github.com/dlang/dmd/blob/09d04945bdbc0cba36f7bb1e19d5bd009d4b0ff2/compiler/src/dmd/target.d#L1177-L1180

Hmmm... Maybe I don't understand. What exactly *is* Alpine Linux 
doing? That .patch file didn't contain anything substantial. It 
looks like it has some version of LDC on hand to use, probably 
already set up properly to use Musl. You're saying that you 
shouldn't need to pass in `-target` because if the compiler was 
compiled with `CRuntime_Musl`, it will just use that 
automatically. But that requires exactly what I don't have: a 
compiler that uses Musl. Am I missing something?
