<pre>When I try to compile the prodkernel with the integrated assembler for PPC, I
get an error while linking saying that `_zimage_start' is duplicated. It looks
like the `arch/powerpc/boot/crt0.S' file specifies that symbol as ".weak", but
clang turns it into a definition:
$ cat ppc-asm.S
.text
.weak _zimage_start
.globl _zimage_start
_zimage_start:
$ clang -target powerpc64-linux-gnu -o /tmp/t.o ../ppc-asm.S -c
$ nm /tmp/t.o
0000000000000000 T _zimage_start</pre>
