config.gcc (sparc*-*-*): Support cpu_32, cpu_64, tune_32 and tune_64. 

2016-05-30  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* config.gcc (sparc*-*-*): Support cpu_32, cpu_64, tune_32 and
	tune_64.
	* doc/install.texi (--with-cpu-32, --with-cpu-64): Document
	support on SPARC.
	* config/sparc/linux64.h (OPTION_DEFAULT_SPECS): Add entries for
	cpu_32, cpu_64, tune_32 and tune_64.
	* config/sparc/sol2.h (OPTION_DEFAULT_SPECS): Likewise.

CC1_SPEC above takes care of this instead.
Note that the order of the cpu* and tune* options matters: the
config.gcc file always sets with_cpu to some value, even if the
user didn't use --with-cpu when invoking the configure script.
This value is based on the target name. Therefore we have to make
sure that --with-cpu-32 takes precedence to --with-cpu in < v9
systems, and that --with-cpu-64 takes precedence to --with-cpu in
>= v9 systems. As for the tune* options, in some platforms
config.gcc also sets a default value for it if the user didn't use
--with-tune when invoking the configure script. */
