Hi, 

I would like to have an integer-simple GHC for Mac and Linux. As there is no official download for that I should probably build it myself. 

My CI server is running Linux containers though. 

When https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling says "build must equal host", does that mean I cannot produce a mac ghc with Linux ci server? How do others produce ghc for mac or Windows? 

Best
Jan
