PowerPC gcc bootstrap fail with bss-plt
git commit 3e04d7655b introduced a bug by sizing output sections earlier in ppc_before_allocation. That meant PLT (and GOT) sizes were not included when calculating total executable section sizes. * emultempl/ppc32elf.em (ppc_before_allocation): Force running prelim_size_sections before deciding whether branch trampolines might be needed.
