    Fix bootstrapping with GHC 7.10.1 · 54884220

    Relying on CallStack being in GLASGOW_HASKELL >= 710 breaks
    bootstrappability with 7.10.1
    
    7.10.2 added the CallStack mechanism, and GHC already relies on this
    while being built. Unfortunately, it is enabled with "GLASGOW_HASKELL
    >= 710", which also applies to GHC 7.10.1, which does not have
    CallStack, and fails building the stage-1 compiler because the symbol
    is not found.
    
    This patch makes the CPP directive more strict, requiring **more than**
    7.10 instead of **at least**.
