allow building webapp with EvilSplicer for non-android arm

Was able to reuse many of the android patches, but several had to be
re-done. On Android, ghc is a stage2 build, so can compile, but not run TH
code. But debian's ghc on armel cannot even compile TH code, so it has
to be patched out.

Some haskell packages have been updated to new versions, including yesod
and DAV, and their patches had to be redone.

The Makefile now has 2 new targets. The first is run on a companion x86
system to do the build and get TH splices. Then the second target is run
the same source tree on the arm system to build without needing TH.
