The fix mainly switches threading libraries and other minor linking stuff.

(should have been -Xf)

Yes. Also note the version numbers in the abitag (currently 504000 meaning
5.4).

Don't. First start to get a simple file working, not directly lazarus. Start
with 2.0.2 cprt0.as and start modifying that. I think that is easier than
working backwards from 2.0.4

There is no TLS in 4.x. So you either left in the tls stuff in your cprt0.as
reconstruction, or you failed to update the preinstalled version (cprt0.o).

Also try to recover link.res when linking fails.
