So, in case the patch from message #5 [1] in this bug report is
applied, please make sure to also patch the settings file for
ghc as above on sparc64 to make sure -Wl,-no-relax is always
used in ghc on sparc64.
I am about to file an upstream bug report in ghc so upstream can
develop a proper fix similar to the older fix for sparc [2].
Cheers,
Adrian
