Bug#1101273: ghc: Pass the mcmodel=medium parameter to CC via GHC

[fanpeng]

Package: ghc
Version: 9.6.6-4+b1
Severity: normal
X-Debbugs-Cc: fanpeng at loongson.cn

Dear Maintainer,

To ensure that GHC-driver builds default to mcmodel=medium, GHC needs
to pass this default parameter to CC without having to add it to the
compiled project.

The former commit does not ensure that all GHC-built object files have
a default model of medium, and will raise an R_LARCH_B26 overflow error.
