PPC NCG: No per-symbol .section ".toc" directives

All position independent symbols are collected during code generation
and emitted in one go. Prepending each symbol with a .section ".toc"
directive is redundant. This patch drops the per-symbol directives
leading to smaller assembler files.

Fixes #18250
