Subject: [PATCH] Pass the mcmodel=medium parameter to CC via GHC
Ensure that GHC-driver builds default to mcmodel=medium, so that GHC
passes this default parameter to CC without having to add it to the
compiled project.
Commit e70d41406b5d5638b42c4d8222cd03e76bbfeb86 does not ensure that all
GHC-built object files have a default model of medium, and will raise an
R_LARCH_B26 overflow error.
