Comment (by erikd):

 Armv7 and Armv8 are not just different ABIs, they are completely different
 architectures (different instructions set even).

 IN addition, however many problems there are with Armv7, the ones with
 Armv7 are significantly worse. Debian shipped a working ghc-7.8.4, but the
 current ghc-7.10.3 is completely busted due to a bug in LLVM that was
 never fixed. I've been using Debian's old ghc-7.8.4 to build the GHC 8.0
 branch, but I currently cannot build Git HEAD because git head requires
 ghc-7.10.
