Log Message:
- Add a post build make target of "make check" to build the tools as 
  we need some of them.  This does not do a full "make check" it just \ 
builds
  the tools.  See patch-ac.
- One of the options in smx.conf (CDB_gid) requires the GID of the smx group
  and as this could change from system to system we do this via the INSTALL
  script using a tool supplied by sendmailX.  It's a bit messy but looks to 
  work OK and the package remains portable.  Hopefully, at some point in time
  they will swap to using the group name as opposed to a GID.
- Fix the phreads detection for 1.x and 2.x. sendmailX should now spot
  native threads on 2.x and GNu Pth on 1.x.
- Initial testing on 1.x shows the build crashing with OpenSSL errors on a
  "make check".  For the moment I'd suggest building without OpenSSL \ 
support
  on 1.x untill this can be looked into fully.
