Rebase after dropping the addition of the dwarf 3 symbols. Just note it here
since it has the same effect in one fewer changes.

I would call the script debuginfo.ldscript instead of debug.

sys/conf/debug.ldscript

Is this still relevant?

Likely not.

Likely not.

Since we have them in the vdso_*.ldscript files, maybe we should remove them from there too?

Could you point me specifically at the place where in vdso scripts we include stabs?

No. We have .comment there

Drop .comment...
Maybe it should be discard?

Ah, we explicitly discard it there... my mistake.

I still think that the script should be renamed to 'debuginfo'.
