[Dovecot] : error while loading shared libraries: libdovecot.so.0 (arm cross compile)

Hi.

Having just removed a number of configure options from the cross compilers  
recipe to simplify the problem I think one of those I took away overrode  
--without-shared-libs.  Now it seems to install and run cleanly.  Even so,  
while building the ipackage I spotted some warnings.  Could these because  
by my build environment?  After some testing I'll let you know if the  
current dovecot build works.  I really appreciate your support and  
patience, thank you.

      The default action is to keep your current version.
