Example error:
/usr/bin/ld: error: can't create dynamic relocation R_386_32 against
symbol: caml_last_return_address in readonly segment; recompile
object files with -fPIC
This port links some non-PIC code, which fails with lld as it defaults
to disallowing relocations against read-only segments. For i386 we can
just add -znotext unconditionally: for GNU BFD ld it just affirms BFD's
existing default.
