Right. I was speaking to Moritz last week (I'm including him in CC),
who forwarded the experience from Sergei Trofimovich on cross
compiling GHC. He did mention this ongoing template-haskell work. But
this doesn't apply to the specific thing we're trying to do, right?
Since we're cross compiling GHC itself and then we'd be running GHC in
the target environment?
