* config/sparc/sparc.h (SPARC_DEFAULT_CMODEL): Default to CM_32.
(CONDITIONAL_REGISTER_USAGE): For block profiling fix %g4 on sparc64,
not %g2.
(MACHINE_STATE_SAVE, MACHINE_STATE_RESTORE): Use %g4 instead of %g2
as sparc64 block profiling register.
* config/sparc/sparc.c (sparc_override_options): Allow block
profiling with -m32.
(sparc_block_profiler): Use %g4 instead of %g2 as sparc64 block
profiling register.
* config/sparc/linux64.h (MACHINE_STATE_*): Only provide these
macros on TARGET_ARCH32. sparc.h has macros good enough for sparc64.
* config/sparc/sol2.h (MACHINE_STATE_*): Likewise.
