Big update of SPARC support for ERC32 and LEON.
Added support for ERC32 without floating point.
Added SONIC support as configured on Tharsys ERC32 board.
The bsp's share various code in the shared directory:
gnat-support, start-up code, etc.
To decrease the foot-print, I removed the 16 kbyte start-up
stack that was put in .bss and never reused once the system
was up. The stack is now put between the heap and the
workspace. To reclaim it, the user can do a rtems_region_extend
to merge the stack to the heap region once the system is up.
