but can't it can't handle gcc LTO:
$ cat test.c
#include <stdio.h>
int main(int argc, char **argv) {
puts("test");
}
$ clang -fuse-ld=lld -flto test.c && echo good
good
$ gcc -fuse-ld=bfd -flto test.c && echo good
good
$ gcc -fuse-ld=lld test.c && echo good
good
$ gcc -fuse-ld=lld -flto test.c && echo good
