ncurses is the only library.

Not sure how I managed to configure the crosscompiler to produce static
binaries, maybe it was an option which I had to pass to GHC. In any case,
here's a docker image which includes instructions how I build the cross
compiler: https://github.com/wereHamster/onion-omega/tree/master/xt, and
here's a docker image which builds on top of that to compile a
cross-compiling GHC:
