ghc and current aarch64

[adr <adr%SDF.ORG@localhost>]

Right now the bootstrap compiler is built in netbsd-8, so it depends
on emulators/compat80, which isn't available to aarch64. So in
current (and I suppose 9 too) you'll end up with:

/usr/pkgsrc/lang/ghc92/work/.tools/lib/ghc-9.2.1/bin/ghc-pkg: Shared object "libcurses.so.8" not found

Has someone crosscompiled a bootstrap compiler for haskell in current
or netbsd-9?
