ok, that is important information. With that I was able to narrow it
down to the "-pie":

$ rm Setup.o; ghc --make Setup.lhs  
[1 of 1] Compiling Main             ( Setup.lhs, Setup.o )
Linking Setup ...
$ rm Setup.o; ghc --make Setup.lhs  -optl -pie 
[1 of 1] Compiling Main             ( Setup.lhs, Setup.o )
Linking Setup ...
/usr/bin/ld: Setup.o: relocation R_X86_64_32S against `stg_CAF_BLACKHOLE_info' can not be used when making a shared object; recompile with -fPIC
Setup.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status

Now someone who knows these flags should investigate if and how this can
be fixed.

Greetings,
Joachim
