pkgsCross.ghcjs.haskellPackages.ghc: don't revert edited config.sub 

GHC ships a [modified] config.sub so that js-unknown-ghcjs is accepted
by autotools. For some platforms, we automatically update config.sub
from upstream's source in order to prevent that builds fail when we use
an outdated config.sub. In this case of course the perfectly up to date
config.sub would reject the target platform we are trying to use, so we
must disable this mechanism for now.

I have asked in the GHC IRC channel if there are any plans on
upstreaming the platform. It would be nice if were able to drop this
change in the future.
