Comment (by erikd):
The Debian package for GHC 8.0 now carries two patches:

Description: Pass -no-pie along with -Wl,-r
GHC uncoditionally passes `-Wl,-r' to gcc in
`compiler/main/DriverPipeline.hs'.
This fails in cases where PIE is enabled by default with the following
error:
.
/usr/bin/ld: -r and -pie may not be used together
.
Fix the above error by passing `-no-pie' along with `-Wl,-r' to the
compiler.
