PR30536, ppc64el gold linker produces unusable clang-16 binary
In commit 0961e631575b, the fix for PR30217, make_lplt_section and
make_brlt_section were changed to use rela_dyn_ rather than their own
separate dynamic reloc sections. This fails miserably whenever brlt_
is needed for long branches, due to needing to iterate sizing and thus
reset brlt_ sizes.

* powerpc.cc (Target_powerpc::make_brlt_section): Don't use
rela_dyn_.
