[Bug target/18603] New: local label names can collide with function names

[wolfgang dot thaller at gmx dot net]

GCC uses local label names .L1, .L2, etc. on this platform.
However these same assembly labels are used for functions named "L1" or "L2".

wolfgang@gorecki wolfgang $ cat L.c
int L2(int x)
{
        if(x > 5)
                return -42;
        else
                return 42;
}
wolfgang@gorecki wolfgang $ gcc -c L.c
/tmp/ccL2lhwX.s: Assembler messages:
/tmp/ccL2lhwX.s:26: Error: symbol `.L2' is already defined

Observed on gentoo powerpc64; also observed on a gcc-3.4.2 cross-compiling from powerpc-apple-
darwin to powerpc64-unknown-linux.
