* config/sparc/sol2.h: Protect -m{cpu,tune}=native handling
with a more complete cpp test.
* config/sparc/linux64.h: Likewise.
* config/sparc/linux.h: Likewise.
* config/sparc/sparc.opt (sparc_debug): New target variable.
(mdebug): New target option.
* config/sparc/sparc.h (MASK_DEBUG_OPTIONS, MASK_DEBUG_ALL,
TARGET_DEBUG_OPTIONS): New defines.
* config/sparc/sparc.c (debug_target_flag_bits,
debug_target_flags): New functions.
(sparc_option_override): Add name strings back to cpu_table[].
Parse -mdebug string. When TARGET_DEBUG_OPTIONS is true, print
out the target flags before and after override processing as well
as the selected cpu. If MASK_V8PLUS, make sure that the selected
cpu is at least v9.
