exim - external DB lookups support not working

[willdeane]

The Exim Makefile includes support for a number of external lookups but they aren't making into the final binary or being added as dynamic libs. I'm specifically looking for postgresql support.
https://github.com/wolfi-dev/os/blob/main/exim/exim.Makefile

The Makefile includes config to build the lookup modules/support:

LOOKUP_CDB=2
LOOKUP_DBM=2
LOOKUP_DNSDB=2
LOOKUP_DSEARCH=yes
LOOKUP_LSEARCH=yes
LOOKUP_MODULE_DIR=/usr/lib/exim/
LOOKUP_MYSQL=2
LOOKUP_MYSQL_INCLUDE=-I/usr/include/mysql
LOOKUP_MYSQL_LIBS=-Wl,--no-as-needed -lmysqlclient
LOOKUP_PASSWD=yes
LOOKUP_PGSQL=2
LOOKUP_PGSQL_INCLUDE=-I/usr/include/postgresql
LOOKUP_PGSQL_LIBS=-Wl,--no-as-needed -lpq
LOOKUP_SQLITE=2
LOOKUP_SQLITE_LIBS=-Wl,--no-as-needed -lsqlite3

The yes indicates the support should be statically compiled into exim and the 2 indicates that they should be complied as dynamic libs. The LOOKUP_MODULE_DIR=/usr/lib/exim/ value specifies where the dynamic libs should be deployed

Building exim from within the wolfi-os dev container (make dev-container) with make package/exim produces a package which which doesn't include any of the dynamic modules:

~ # apk info -L exim
exim-4.98-r1 contains:
etc/exim/exim.conf
etc/mail/aliases
usr/sbin/exim
usr/sbin/mailq
usr/sbin/newaliases
usr/sbin/rmail
usr/sbin/rsmtp
usr/sbin/runq
usr/sbin/sendmail
usr/share/man/man8/exim.8
var/lib/db/sbom/exim-4.98-r1.spdx.json
~ # 

Logs from the build suggest the shared libs are being built:

I think the libs are being built but not packaged by melange

Alpine is using an almost identical make file but provides additional packages for each dynamically built lib - https://github.com/alpinelinux/aports/blob/master/community/exim/exim.Makefile
