 While trying to build GHC 8.4.2, we face the following error:

 {{{
 [15143s] ghc-stage1: panic! (the 'impossible' happened)
 [15143s]   (GHC version 8.4.2 for arm-unknown-linux):
 [15143s]        Failed to lookup the datalayout for armv7l-unknown-linux-
 gnueabihf; available targets: ["i386-unknown-windows","i686-unknown-
 windows","x86_64-unknown-windows","arm-unknown-linux-gnueabihf","armv6
 -unknown-linux-gnueabihf","armv7-unknown-linux-gnueabihf","aarch64

 -apple-ios","i386-apple-ios","x86_64-apple-ios"]
 }}}

 So, we should add armv7l-unknown-linux-gnueabihf to ./utils/llvm-targets
 /gen-data-layout.sh and regenerate llvm-targets file.
