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.
