[Dovecot] Imap segfault on login with version 2.0.8 & 2.0.11

Don't know if this is related:
I had a problem with dovecot-2.0.11 under AIX 5.3, it segfaulted right
after connect. The reason was that struct login_binary remained 
uninitialized in login-common/main.c
The problem disappeared after configuring with --disable-shared.
Maybe this is worth a try.

Regards,
Klaus
