Backport note: I have ported `uncacheModule` instead of removing it as
is done in 0d170eafacba55325dc00d0434d4462275d4376e since the necessary
type change is likely easier for possible GHC API users to accommodate
than outright removal.

This patch makes the driver always merge objects with `ld -r` when
possible, and only fall back to calling `ar -L` when merge objects
command is unavailable. This completely reverts !8887 and !12313,
given more fixes in Cabal seems to be needed to avoid breaking certain
configurations and the maintainence cost is exceeding the behefits in
this case :/

This commit was wrong, as noted in the `master` revert cfeb70d3fed9c135295359296208bd800bab418f.
It appears to have ultimately been superceded by 0fe2b410ac0d8951f07ffcc9f3c6c97bc312df48
