Support PIE on Solaris
gcc/testsuite:
* lib/target-supports.exp (check_effective_target_pie): Check for
PIE support on Solaris 11.x and 12.
libgcc:
* config.host (*-*-solaris2*): Add t-crtstuff-pic to tmake_file.
Add crtbeginS.o, crtendS.o to extra_parts if libgcc_cv_solaris_crts.
* config/sol2/gmon.c: (monstartup): Don't write trailing NUL of
messages.
(internal_mcount): Likewise.
* config/sol2/t-sol2 (crtp.o, crtpg.o, gmon.o): Compile with
crt_compile, add CRTSTUFF_T_CFLAGS_S.
gcc:
* configure.ac (gcc_cv_ld_pie): Check for gld >= 2.26 on Solaris.
Check for ld -type pie on Solaris 11.x and 12.
* configure: Regenerate.
* config.in: Regenerate.
* gcc.c (LD_PIE_SPEC): Allow redefinition.
* config/sol2.h (STARTFILE_CRTBEGIN_SPEC): Define.
(STARTFILE_SPEC): Use it.
(ENDFILE_CRTEND_SPEC): Define.
(ENDFILE_SPEC): Use it and ENDFILE_ARCH_SPEC.
(SUBTARGET_EXTRA_SPECS): Add STARTFILE_CRTBEGIN_SPEC,
ENDFILE_ARCH_SPEC, ENDFILE_CRTEND_SPEC.
[HAVE_LD_PIE && HAVE_SOLARIS_CRTS] (LD_PIE_SPEC): Define.
(!(HAVE_LD_PIE && HAVE_SOLARIS_CRTS)] (LINK_PIE_SPEC): Define.
* config/i386/sol2.h (ENDFILE_SPEC): Remove.
(ENDFILE_ARCH_SPEC): Define.
* config/sparc/sol2.h (ENDFILE_ARCH_SPEC): Define.
