FYI: DMD has been using -fPIC by default on Linux x86_64 since 2.072.2
too:
https://github.com/dlang/dmd/pull/6359
It's just that the Makefile scripts in dmd, druntime and phobos reset
the predefined flags with `-conf=` (aka the backdoor) and thus a lot of
manual updating was required.

So simply add -fPIC to DFLAGS or maybe even hard-code it like it's
done for macOS:

Thanks for finding all the PR's related to this issue.
I will look into as soon as my current project is finished. Can only
concentrate on one thing at a time :-)
Yep, just defaulting to -fPIC should be perfectly workable. LDC has
been doing this since the first Ubuntu version requiring PIC was
released (16.10?), and we haven't had any complaints so far. Since I'm
not sure DMD has a way of negating -fPIC once it has been set, just
adding it to the default config file is probably the best approach, as
it leaves a backdoor open for users wanting to build non-PIC code.
Best,
David
