GHC-7.10.1 compatibility

[nomeata]

Hi,

if Travis is not misleading me, then cassava has no version compatible with GHC-7.10.1 (which ships ghc-prim-0.4) due to ghc-prim (>=0.2 && <0.4).

Thanks,
Joachim

👍 I need this too. I think every benchmark program that uses on Criterion is now broken because of this.

Btw, cassava probably doesn't need ghc-prim anymore for GHC >= 7.6 anyway...

PS: See also #82 which drops the ghc-prim dep for GHC >= 7.6 (btw, I used the same technique in the latest deepseq version)

FYI, building it without the ghc-prim dependency and relaxing blaze-builder to < 0.5 (instead of < 0.4) works for me (i.e. passes cabal config / cabal build / cabal test) on a freshly built GHC 7.10.1

Fixed.
