This will need some more work. Currently
termux_create_haskell_debscripts is run for all packages, even
non-haskell ones, which causes errors in postinst and prerm scripts in
an ugly way.
This reverts commit dc2474b2c2.
- `termux_setup_ghc_cross_compiler` should not be called by build.sh, as it installs cross-compiler
in $TERMUX_PREFIX (otherwise ghc adds wrong `rpaths` to built libs and executables)
