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.
(cherry picked from commit 7df6aecc97b96843da080d54414052b1c954ddca)
