Comment (by trommler):

 Replying to [comment:37 pkubaj]:
 > So it looks like {{{binary-dist}}} step is wrong. I'll soon upload a
 full log.
 No, it is fine. A binary dist is prepared so the files in it can be
 installed, and
 for that it doesn't need most of the `inplace` scripts.

 Here we are at something. `libgcc_s.so.1` is taken from `/lib` while it
 should be coming
 from `gcc8`. Did you set `CFLAGS` and`LDFLAGS` to also point gcc's
 directory on powerpc64
 (with `-Wl,rpath=...`) when you were building on amd64?

 Could you also post the output of `readelf -d /usr/local/lib/ghc-8.6.3/bin
 /ghc-pkg` on
 powerpc64? I am only interested in lines that contain `RUNPATH` or
 `RPATH`.
