hspell: fix cross-platform build issues
hspell: fix cross-platform build issues

hspell uses a couple of binaries it generates during it's own build.
These will cause the build to fail later in cross-platform builds as
these binaries have the wrong executable format.
Using a hspell to bootstrap it's own build natively resolves this issue.
