An additional note - it may well be a ld version issue. On Ubuntu
the ld version is 2.30, but on Fedora ld reports 2.31.1-13.fc29.
(Maybe I should have held off upgrading to Fedora 29...)

Looking at this a little more I think the headers are simply not
available to the program. Simply commenting out the INITTLS call
allows the compiler to be built successfully. I note that
multi-threaded programs don't call it (at least those using
cthreads) and if the program isn't multi-threaded the call to
INITTLS is most likely not needed so I suspect this would fix most
use cases. My main non-gui program (multi-threaded) runs fine.
However on Fedora 29 32 bit builds on 64 bit systems are broken
for lazarus because the 32 bit -devel packages are broken:
https://bugzilla.redhat.com/show_bug.cgi?id=1651231
https://bugzilla.redhat.com/show_bug.cgi?id=1645328
so maybe I should just conclude that 32 bit apps are broken on
Fedora.

Can you test if patch from my bug report
<url:https://bugs.freepascal.org/view.php?id=34475> fixes your
problem? You can omit changes for x86_64 target from that patch.

This is loader-abitag.diff? With that applied, both 64 and 32 bit
fpc trunk build, and basic testing indicates that they are working
fine. I note however that compiling a basic "Hello World" program
now produces a dynamically linked, rather than a statically linked
executable, and INITTLS is not called.

Strange. All my (32/64 bits) binaries are static ones.
What I can see at seeing the source code is that INITTLS is only
defined for i386 target.

Oh, I forgot to mention that I use Arch Linux. I run the i686 and
x86_64 versions of Arch as an LXC containers.

Sorry - my statement about "Hello World" producing a dynamically linked
executable was wrong - I must have mixed up the source file. It now
behaves as I would expect, and can recommend your patch. I will add a
note in the bug tracker
