[GHC] #10476: Wrong ar during cross-compilation

It will cause linking errors on systems where ar for target architecture is incompatible with ar for build/host architecture (sample output attached below). {{{ (...)

Will rerun the build and look for this command in the output later. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10476#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

What does your bootstrap compiler output for `ghc --info` under `("ar command",___)`? That command should end up as the value of `AR_STAGE0` in `mk/config.mk`, and then get run for `ar` here since `bin-package-db` is a stage 0 package. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10476#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
