Hi,

with ld it's possible to provide a linker script as an input, just like an
object file.

This doesn't seem to work with lld on MinGW. It works as expected on linux.

$ cat test.cpp
#include <iostream>

int main(int argc, char **argv)
{
    std::cout << "Hello world!" << std::endl;
    return 0;
}

$ g++ -c test.cpp

$ cat link_script
INPUT(
./test.o
);

$ g++ -o test.exe link_script

$ g++ -fuse-ld=lld -o test.exe link_script
lld-link: error: link_script: unknown file type
collect2.exe: error: ld returned 1 exit status

$ g++ -v -fuse-ld=lld -o test.exe link_script
Using built-in specs.
