--- Comment #67 from mintsuki <mintsuki at protonmail dot com> ---
I'd like to give a summary of the issue, as the whole thread is pretty long and
may get confusing:

ld.bfd, *regardless of target*, be it GNU/Linux or even *freestanding
environments* (for example using an x86_64-elf binutils toolchain), generates
perfectly fine relocatable PIE ELFs with proper PT_DYNAMIC segment and all, but
with ELF type ET_EXEC, when the base load address is non-0, as this was added
as some coarse workaround for some GNU/Linux specific issue.

This is a bug. It should be fixed, as ld.bfd doesn't exist in a bubble where it
only builds executables for GNU/Linux necessitating some questionable
workaround. Additionally, both ld.lld and ld.gold do not have this bug.

What's worse: this[1] issue was opened against LLD requesting that the bug be
added to LLD!

Please, just revert the 2013 "workaround" for GNU/Linux or make it less coarse,
and fix this bug.
