# GHC requires GHC to build itself. Formerly we could work around this
# bootstrapping problem by creating a special archive containing C
# sources compiled from Haskell sources, but that's no longer
# possible. So we have to prepare stripped-down binaries sufficient to
# bootstrap compilers for each platforms. If you want to build them
# yourself, follow an instruction in the ./TODO file.
