 /usr/bin/ld: -r and -pie may not be used together

 http://lpaste.net/159726

 It appears on Archlinux, with GCC version 5.3.0, there's an implicit -pie
 flag passed to `ld`. I looked into compiler/main/DriverPipeline.hs at
 joinObjectFiles, it is unconditionally doing "-Wl,-r", thus the error
 above.

 One suggested fix on IRC is to modify getCompilerInfo to know if it
 supports -no-pie, then add it to the flags that are used. I tried and got
 somewhere lost in compiler/main/DynFlags.hs. (Completely new to GHC)

 Hopefully someone can figure it out, it seems important for development
 and I really want to get involved :)
