Thanks, the worked like a charm! Any chance this can be used for cross-compiling from a Unix desktop to embedded arm?

Not as easy as that. This solution relies on the fact that you can run i386 binaries on x86-64, which is obviously not true for arm.

Yeah, I sort of expected that. But i'd be nice if it works.

See https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling for how to build a cross-compiler.

Doesn't work for me for building embedded code. The target arm-none-eabi fails to configure because gcc doesn't work, because _exit doesn't exist. Which is indeed the case. I don't see any way to turn that off. Is this not supported by ghc?
