alpha: discard .eh_frame and the relocation sections

gcc emits .eh_frame for Alpha even though the kernel builds with
-fno-asynchronous-unwind-tables, and nothing in the kernel consumes it:
the stack trace code scans the stack for text addresses rather than
unwinding DWARF.  It was allocated in the loaded image, so dropping it
shrinks vmlinux by about 1.1MB for a Marvel SMP configuration.

The .rela* sections are equally useless, as the kernel image is not
relocatable.  The linker was already dropping their contents.

Both were being placed as orphan sections, which is what drew attention
to them.
