Comment:

 Detection of this probelms was added to the ghc-7.10 branch in:

 {{{
 commit b856f3f3d7850ca0456dd80aaa59241b3d297ab9

     configure: Test for #9920 when compiling for arm

     The ghc-7.10 branch requires use of llvm-3.5, but the llvm-3.5.0
     release had a bug that was fixed in llvm-3.5.1.

     When we are targeting arm, test for this bug in the llvm program
     `llc` during confgure and if present, abort configuration with
     an informative error message.
