> As an update, I have been trying to build and find a solution for this
with boklm's changes above, and it fails with a similar error to the one
boklm had.

a higher entropy for HEASLR. Since that is not working for us, how about
we just go with `-Wl,--high-entropy-va` for now till we find a solution?
What prevents us from finding that out now? Did you try to use
`-mcmodel=medium` or `-mcmodel=large`? Why is ffpmeg not hitting the dwarf
related problem in the first place? I.e. why is the linker not complaining
for them?
