Use CRTs provided by Solaris

	gcc:
	* configure.ac (gcc_cv_solaris_crts): New test.
	* configure. Regenerate.
	* config.in: Regenerate.
	* config/sol2.h (STARTFILE_SPEC): Simplify, provide
	HAVE_SOLARIS_CRTS variant.

	libgcc:
	* configure.ac (libgcc_cv_solaris_crts): New test.
	* configure: Regenerate.
	* config.in: Regenerate.
	* config/sol2/crtp.c, config/sol2/crtpg.c: New files.
	* config/gmon-sol2.c: Rename to ...
	* config/sol2/gmon.c: ... this.
	Include auto-target.h.
	(internal_mcount): Wrap setup handling in !HAVE_SOLARIS_CRTS.
	* config/t-sol2: Rename to ...
	* config/sol2/t-sol2: ... this.
	(gmon.o): Reflect renaming.
	(crtp.o, crtpg.o): New rules.
	* config.host (*-*-solaris2*): Reflect renaming.
	Use system CRTs if present.
	Remove default CRT case.
