Update to the GCC 3.4.6 release, which concludes the GCC 3.4 release
series. Move from tracking snapshots to the official release sources,
which requires an EPOCH bump, unfortunately.
Remove the cklatest target which we just do not need any longer.
Always build both shared and static libraries instead of having these as
two exclusive options defaulting to the former.
Fix handling of shared libraries via rc.d for non-default prefixes and
move the rc.d script from PLIST_FILES to pkg-plist.
Do not strip some of the the binaries any longer.
No longer hardcode the version number in LATEST_LINK.
