If your module name isn't Main, you have to tell GHC what to regard as the 
main module by passing the "-main-is" flag on the command line

$ ghc -O2 --make -main-is Test -o Test Test.hs

works. And your main function may also have a different name, e.g.

$ ghc -O2 --make -main-is MultiMain.main2 -o main2 MultiMain.hs

with

module MultiMain where

main1 :: IO ()
main1 = putStrLn "main1"

main2 :: IO ()
main2 = putStrLn "You chose main two."
