riscv64: Test failures due to linker warning: creating DT_TEXTREL in a PIE

[alexfanqi]

Hi,
I am testing ocaml 4.12.1 on riscv64 (sifive unmatched board) on Gentoo and running gcc-11.2.0 and glibc-2.33. I had some test failures due to the same cause, example:

Running action 3/8 (check-ocamlopt.byte-output)

This seems to have happened for 32 bit arches previously #9800. After discussed with one contributor there, the original issue is not the case here because ocamlopt support generating PIC for riscv64. so I open a new issue here. Happy to provide more info if needed.
