If we generate an object file using an assembler with the new
relocations added, and then linking those files with an older
linker, the link will still complete and the linked file will
be generated.
In this case we should report an error instead of continuing
the linking process.

The md_pre_output_hook creating fixup is asynchronous, causing relocs
may be out of order in .eh_frame. Define GAS_SORT_RELOCS so that reorder
relocs when write_relocs.

A bug in ctf_dtd_delete led to refs in the string table to the
names of non-root-visible types not being removed when the DTD
was. This seems harmless, but actually it would lead to a write
down a pointer into freed memory if such a type was ctf_rollback()ed
over and then the dict was serialized (updating all the refs as the
strtab was serialized in turn).
Bug introduced in commit fe4c2d5563
("libctf: create: non-root-visible types should not appear in name tables")
which is included in binutils 2.35.

* ctf-create.c (ctf_dtd_delete): Remove refs for all types
with names, not just root-visible ones.
This fixes miscounting of dynamic relocations on GOT entries when
a) there are both local-dynamic and global-dynamic tls accesss for a
given symbol, and
b) the symbol is global with non-default visibility, and
c) the __tls_get_addr calls aren't optimised away.

DT_RELACOUNT was calculated incorrectly, and relative relocs not
sorted as they should be to the start of .rela.dyn, due to adding one
particular class of dynamic reloc using the wrong "add" method.
* powerpc.cc (Target_powerpc::Scan::global): Add relative
dyn relocs for ADDR64 and similar using add_global_relative.

In commit 0961e63157, 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.

rela_dyn_.
