split-obj: disable split-objects on Windows.
A change has caused GHC to generate excessive specializations.
This is making GHC generate 1800 splits for a simple GHC.Prim module,
which means 1800 fork/exec calls.
Due to this compilation times on Windows with split-objs on take over
24 hours to complete depending on your disk speed. Also the end
compiler
compiling medium to large project is also much slower.
So I think we need to just disable split-objects. As there's nothing
that
can be done about this.
