Would it be worth transferring that comment into the building guide (a cross-compiling page perhaps). The distinction is subtle and the information is useful
There is http://hackage.haskell.org/trac/ghc/wiki/CrossCompilation
but I'm not sure it has this info

| Tidy up cross-compiling
|
| We have two cases:
| 1. building a cross-compiler
| 2. compiling GHC to run on a foreign platform
|
| These two are done with almost the same setup: (1) is the stage 1
| compiler, and (2) is the stage 2 compiler, when CrossCompiling=YES.
|
| The only difference between (1) and (2) is that you if you set up
| the
| build for (1), then it stops before stage 2 and you can 'make
| install'
| to install stage 1.
|
| Unfortunately, (2) didn't work, and the build system code needed
| some
| tidying up.
|
| Change to the way the build is set up:
|
| Before
| ------
|
| To build a cross-compiler:
| ./configure --target=<..>
|
| To compile a foreign GHC:
| ./configure --host=<..> --target=<..>
|
| Now
| ---
|
| To build a cross-compiler:
| ./configure --target=<..>
| And set "Stage1Only=YES" in mk/build.mk
|
| To compile a foreign GHC:
| ./configure --target=<..>
