Bug 139: portability fixes and documentation.

Document the dynamic lookup module capability in spec.xfpt.
Include a ChangeLog item.

Avoid the GNU-specific "export" make(1) directive.
Build the lookups Makefile using the existing framework.
Build with BSD Make once more.

The src/lookups/Makefile that is used at build time now has the dynamic
content come from scripts/lookups-Makefile.

Add CFLAGS_DYNAMIC support, which can be set in Local/Makefile.
Provide defaults for Linux & FreeBSD.

Ensure that build fails early if a dynamic module is requested but
CFLAGS_DYNAMIC is not defined.

+.section "Dynamically loaded lookup module support" "SECTdynamicmodules"
+.cindex "lookup modules"
+.cindex "dynamic modules"
+.cindex ".so building"
+On some platforms, Exim supports not compiling all lookup types directly into
+the main binary, instead putting some into external modules which can be loaded
+on demand.
+This permits packagers to build Exim with support for lookups with extensive
+library dependencies without requiring all users to install all of those
+dependencies.
+Most, but not all, lookup types can be built this way.
+
+Set &`LOOKUP_MODULE_DIR`& to the directory into which the modules will be
+installed; Exim will only load modules from that directory, as a security
+measure.  You will need to set &`CFLAGS_DYNAMIC`& if not already defined
+for your OS; see &_OS/Makefile-Linux_& for an example.
+Some other requirements for adjusting &`EXTRALIBS`& may also be necessary,
+see &_src/EDITME_& for details.
+
+Then, for each module to be loaded dynamically, define the relevant
+&`LOOKUP_`&<&'lookup_type'&> flags to have the value "2" instead of "yes".
+For example, this will build in lsearch but load sqlite and mysql support
+on demand:
+.code
+LOOKUP_LSEARCH=yes
+LOOKUP_SQLITE=2
+LOOKUP_MYSQL=2
+.endd
