I know nothing about active development of x32 unfortunately. But it is not only for it, it is generic one.

That patch is for both x86 and x64 (R_I386_IRELATIVE vs R_X86_64_IRELATIVE) but that feature exists for other targets such as aarch64 (R_AARCH64_IRELATIVE), powerpc (R_POWERPC_IRELATIVE). gold has support it for.

As far I understand the main use case now is linking against libc.a with multi-arch enabled:
