Since no one responded I will try.

My guess is that for the current official release of epics you are
out of luck. You can, however, do the following:

1) Prepare a default.dctsdr of a big endian machine (sun or hp
   work for sure). Load this into ioc with dbLoad before loading
   any record instances.
2) Prepare all record instances in the gdct .db format, which is 
   completely ascii. This can be loaded with dbLoadRecords and/or
   dbLoadTemplates.

In the next release of epics ALL database definition files will
be loaded from ascii files, i.e. default.dctsdr will go away.
At this time the big vs little endian problem disappers for
ioc epics databases.
