We haven't done it ourselves. Why don't you give it a try? It shouldn't
take long to do so. Roughly, the steps are as follows:

1. Create a platform file:
       <top>/mk/platforms/sparc_linux_2.2_glibc2.1.mk
    You can start by copying i586_linux_2.0_glibc2.1.mk
    You can reuse all the settings in the file except:
       1. IMPORT_CPPFLAGS 
            change __x86__ to __sparc__

       2. Change x86Processor = 1 to SparcProcessor = 1
          (This is however not essential.)

2. Specify the byte order in <top>/include/omniORB3/CORBA_sysdep.h
      Look for the relevant section and add:
         #elif defined(__sparc__) && defined(__linux__)
         #define _OMNIORB_HOST_BYTE_ORDER_ 0
       
3. Is long in gcc-Sparc64 32-bit? If so there is nothing to do.
   Otherwise you may have to define SIZEOF_LONG like that for alpha.


That is it. Compile and try it out.
