New target powerpc64 symbol collision

[Dan Schatzberg <schatzberg.dan@xxxxxxxxx>]

I am trying to add a new OS target to gcc 4.7.1. In particular I am
focused on the powerpc64 architecture. I've modified the gcc 4.7.1
source to add my target. I've managed to build a cross compiler for my
target but I had a problem:

sample code test.c:
void foo() {}

output of gcc test.c -S:

.file "test.c"
.section ".text"
.align 2
.globl foo
.section ".opd","aw"
.align 3
foo:
.quad foo,.TOC.@tocbase,0
.previous
.size foo,24
.type .foo,@function
.globl .foo
foo:
stdu 1,-32(1)
std 31,24(1)
mr 31,1
addi 11,31,32
ld 31,-8(11)
mr 1,11
blr
.size foo, .-foo
.ident "GCC: (GNU) 4.7.1"

GCC introduces the same symbol twice which fails to assemble. I would
expect the second "foo" symbol (and corresponding references) to just
be a local symbol like ".L.foo". What do I need to change to see the
correct behavior? Thanks
