riscv-non-isa/riscv-elf-psabi-doc#71 (2021-06) added PT_RISCV_ATTRIBUTES, but
no dynamic loader uses this yet.

I created https://reviews.llvm.org/D152065 to add PT_RISCV_ATTRIBUTES to
ld.lld.

This looks like a GNU objcopy/strip bug. The tool should work regardless of
whether the linker creates PT_RISCV_ATTRIBUTES. AArch32 doesn't have
PT_ARM_ATTRIBUTES and I believe objcopy/strip can process such a trivial
program. The RISC-V port should be fixed.
