dev-lang/ghc: add big-endian ppc64 binary

This requires a patch to work correctly on BE systems.  Apply the patch
unconditionally since it is already includes the appropriate checks in
the code.  Delete a few lines of commented-out obsolete patches.

+Subject: [PATCH] Disable unboxed arrays on big-endian
+
+Unboxed arrays are broken on big-endian architectures, see
+https://gitlab.haskell.org/ghc/ghc/-/issues/16998 for details.
+This patch makes the use of unboxed arrays conditional on
+little-endian architecture.
+
+Fixes #673
