- insist on using pass_all systematically everywhere on OpenBSD.
libtool can't be trusted with that, the darn stupid thing wants a shared
libgcc half the time.
- acknowledge that build won't even work without shared libraries. There
are symbol collisions all over the place.
- disable debugging messages, so that the result looks sane.
- remove the konsole kludge, it didn't work anyways, and I figured out how
to do it from konsole_grantpty.
- insist on using zsh in sh compatibility mode instead of our somewhat
buggy ksh.
