A number of small-but-important updates:
1. Update the names of some configure flags. This would not have affected
users who used the defaults, or the package.
2. In order for the speller option to actually be chosen by configure
it already has to be installed, so add them to BUILD_DEPENDS. [1]
Fixing this properly also required a patch to configure which I am
submitting upstream.
3. Update the location of mlock (if installed) [1]
4. Turns out that alpine no longer uses the value of SSLTYPE internally,
(it is only used by the IMAP server which we don't build) so simplify
the whole SSL section considerably. All authentication types are now
available to alpine by default.
5. Include the proper MAKE_ARGS and relax a test in configure to give
users who want to try the new S/MIME support a fighting chance. [2]
Bump PORTREVISION accordingly
