RISC-V: Protect .got with relro
Move .got before .data so that it can be protected with -zrelro. Also
separate .got.plt from .got if -znow is not in effect; the first two words
of .got.plt are placed within the relro region.

It causes the elf/audit1 elf/tst-audit2 elf/tst-audit8 glibc tests to fail with
a segmentation fault if configured with --enable-bind-now. It appears to be a
bug in glibc.

Thanks for looking at that, it makes sense. Do you plan to work on that, or
should I look what I can do?

RISC-V: Add support for dl_runtime_profile (BZ #31151)
Code is mostly inspired from the LoongArch one, which has a similar ABI,
with minor changes to support riscv32 and register differences.
This fixes elf/tst-sprof-basic. This also fixes elf/tst-audit1,
elf/tst-audit2 and elf/tst-audit8 with recent binutils snapshots when
--enable-bind-now is used.
Resolves: BZ #31151
