If I recall correctly, kernel single-step support is a relatively new
feature in Solaris.  If you know that you'll only run GDB on versions
that support it, you probably can get away with disabling SOFTWARE_-
SINGLE_STEP_P locally.  I'm not sure what would be required to get it
into the mainline GDB.  It would either have to be a new config, or 
be able to determine whether or not kernel single-step is available
at run-time.
