We have long transitioned to PIE by default on all release architectures
now. Still each gcc-V package tracks the architectures that enable PIE
by default in an opt-in list (pie_archs).

Since it is the default, PIE is much better supported than !PIE now.
For instance, musl-linux-mips fails building dash, because ld segfaults.
Once enabling PIE for musl, it proceeds. Similarly, x32 fails linking
systemd and it obviously is connected to !PIE:

    ld: /tmp/cc9ezYWe.ltrans0.ltrans.o: relocation R_X86_64_32S against `.rodata' can not be used when making a PIE object; recompile with -fPIC

Very likely, the riscv64 people want to enable PIE by default as well.

Since it practically is the default "everywhere", can we move on to
enable PIE for all "new" architectures by turning the opt-in list
opt-out? While at it, can we keep this list as small as possible? At
least for musl-linux-any and x32, we know that !PIE causes more harm
than PIE.

I've Cced this to d-devel to have people object, but I think the case is
pretty clear at this point, because opt-out will reduce the maintenance
cost.

The attached patch implements opt-in. It does not change x32 to be
conservative. It does change musl to keep the list short, but there is
no relevant Debian musl deployment anyhow.
