[PATCH 2/2] powerpc/vmlinux.lds: Discard .interp section

The .interp section specifies which "interpreter", ie. dynamic loader,
the kernel requests. But that doesn't make any sense, the kernel is
not a regular binary that is run with an interpreter.

The content seems to be some default value, this file doesn't even
exist on my system:
  00000000  2f 75 73 72 2f 6c 69 62  2f 6c 64 2e 73 6f 2e 31  |/usr/lib/ld.so.1|

So the section serves no useful purpose and consumes a small amount of
space.

Also Alan Modra says we "likely could discard" it, so do so.
