[PATCH] arch/powerpc: Remove .interp section in vmlinux

[Vishal Chourasia]

While debugging a ppc64le QEMU guest on an x86_64 host, I observed GDB crashes
when attempting to attach to the remote target:

(gdb) target remote :1234

Investigation revealed that cross-compiling the Linux kernel for ppc64le on an
x86_64 host using Clang produces a vmlinux binary containing an empty .interp
section. This empty .interp section is responsible for the GDB crashes.

This issue does not occur when:
- Building for ppc64le target using GCC on x86_64 host
- Building for ppc64le target using Clang on ppc64le host  
- Building for ppc64le target using GCC on ppc64le host
