Subject: [PATCH] - Move _Qp_* and __dtoul from FBSDprivate to the list of
 FBSD_1.0 symbols   as well as add __sparc_utrap_install to FBSD_1.0; these
 are required by   the SCD libc 64 psABI and thus meant to be officially
 exported symbols. - Remove the __fpu_* entries as well as the __sigtramp
 entry altogether as   these are internal to the libc FPU emulation and the
 signal trampoline   initialization in sigaction(2) respectively and thus
 don't need to be   externally visible. - Add __sparc_utrap_setup to the list
 of FBSDprivate symbols as it's used   in src/lib/csu/sparc64/crt1.c to
 initialize the libc FPU emulation (I   think alternatively
 src/lib/csu/sparc64/crt1.c could be changed to use   __sparc_utrap_install
 instead, at the expense of increasing the size of   executables a bit). - Add
 an entry for the vfork symbol to the FBSD_1 list and entries for it's  
 associated symbols generated by the RSYSCALL() macro to the FBSDprivate  
 list. There's some magic in place that automatically generates code for  
 vfork() if there's no explicit MD code for it so it might make sense to  
 move these symbols from the MD symbol map files to a MI one.

The last two changes make the libc symbol versioning useable on sparc64.
