Thanks Adam for the tip about dynamic linking, as always.
He was right that the debug information was in the relevant .so files
and that when I statically linked GHC the information was included (as
with cabal). The issue was my program which read the dwarf information

dynamic libraries? If your GHC is dynamically linked the library DWARF info
might be available in their respective .so's.

So I added these flags to may hadrian.settings file
stage1.*.ghc.hs.opts += -g3
stage1.*.cabal.configure.opts +=
