Comment (by basvandijk):

 As I [https://github.com/NixOS/nixpkgs/issues/55848#issuecomment-464212640
 just discovered], apparently my `libc++.a` in my Nix store contains the
 following:

 {{{
 > cat /nix/store/jv40yw2ny28nnpbf860aaqq1dhga0f0r-
 libc++-5.0.2/lib/libc++.a
 INPUT(-lc++_static -lc++abi)
 }}}

 Note that the first 8 bytes of this file are `INPUT(-` which is exactly
 what GHC is panicking about. It seems that GHC is expecting `libc++.a` to
 be a binary archive while in fact it's some kind of textual reference to
 the real archive `libc++_static.a` which can be found in the same
 directory.

 Are these textual archive file a Nix-specific thing that GHC doesn't
 support?
