Force building with ghc-9.6.5

The default makepkg configuration sets LDFLAGS but not LD.
GHC used to take this as its cue to select its own choice of LD.
However GHC would *not* check that its choice of LD supports LDFLAGS.
This is a problem for dependencies with C components, which get linked
using this LD.

A fix[1] for this has landed in ghc 9.6.5 on 2024-04-16, and ghc's
installed using the current ghcup HEAD (starting with 7a684ad[2]) will
have `--disable-ld-override` passed, which also fixes the issue.
