There's an FAQ entry on this topic on the Haskell Stack page.

After you see this error, do the following:

cd /tmp/Hs2lib924498/
ghc -fglasgow-exts --make -shared -oHs2lib.a /tmp/Hs2lib924498/Hs2lib.hs dllmain.o -static -fno-warn-deprecated-flags -fPIC -O2 -package ghc -package Hs2lib -i/home/phyx/Documents/Haskell/Hs2lib -optl-Wl,-s -funfolding-use-threshold=16 -optc-O3 -optc-ffast-math

Note I added -fPIC to the failed ghc command.

Once the command succeeds, continue the compilation from within the tmp directory without cleaning already compiled files. It should skip them and continue where it ended.
