    ## Environment
- **Target**: PowerPC
- **Host**: X86
- **Build command**: `make LLVM=1 ARCH=powerpc -j $(nproc) vmlinux`

## Issue
LLD generates vmlinux with an empty `.interp` section, causing GDB to crash when connecting to QEMU:

```bash
gdb vmlinux
(gdb) target remote :1234  # crashes here
```


```bash
$ make LLVM=1 ARCH=powerpc  -j`nproc` vmlinux  # works fine
$ llvm-readelf -p .interp vmlinux
String dump of section '.interp':

```

## Expected Behavior
The kernel should not have a `.interp` section. GNU ld does not emit this section:

```bash
$ make LLVM=1 ARCH=powerpc LD=powerpc64le-linux-gnu-ld -j 8 vmlinux  # works fine
$ llvm-readelf -p .interp vmlinux
llvm-readelf: warning: 'vmlinux': could not find section '.interp'
```

## Impact
Breaks kernel debugging with QEMU+GDB for PowerPC builds using LLVM.
