Subject: `musl-gcc -static` and lld/mold


I think I found a musl-gcc issue. It looks like musl-gcc always appends
`-dynamic-linker /lib/` even if `-static` is given. That
causes a created program to immediately crash on startup as you can see

$ cat hello.c
#include <stdio.h>
int main() { printf("Hello\n"); }

$ musl-gcc -static -fuse-ld=lld hello.c -o hello

$ ./hello
Segmentation fault (core dumped)

$ musl-gcc -static -fuse-ld=lld hello.c -o hello -Wl,-no-dynamic-linker
$ ./hello

This also happens to my new linker, mold, as well. `-dynamic-linker` option
is passed to the linker, and lld and mold do what it is told to do, so I
don't think it is a linker's bug. Rather, it's a compiler front end's bug
that passes the unnecessary command line option. Can you not to append
`-dynamic-linker` if `-static`?
