I'm indeed a bit unsure whether that's a good idea if PIE support hasn't
been tested much on those distributions. OTOH it's in widespread use to
harden at least some security relevant programs, and gcc has PIE support
since quite a while.
Also PIE isn't much magic other than PIC plus changing the ELF file type
(to DYN instead of EXEC).

Supporting different variations also comes at a cost (e.g. asking back
in bug reports).
And as we've switched the generic linux.tar release to support PIE, it
might make sense for most distributions.

Enabling -fPIC for executables is not equivalent to enabling PIE for D,
the ELF file format still remains a gcc -pie/-no-pie option and
distribution default.
