Support SHF_EXCLUDE on non-x86 and with Solaris as

	* configure.ac (gcc_cv_as_section_has_e): Move to common section.
	Rename to...
	(gcc_cv_as_section_exclude): ... this.
	Try Solaris as #exclude syntax.
	* configure: Regenerate.
	* config.in: Regenerate.
	* config/i386/i386.c (i386_solaris_elf_named_section): Handle
	SECTION_EXCLUDE.
	* config/sparc/sparc.c (sparc_solaris_elf_asm_named_section)
	[HAVE_GAS_SECTION_EXCLUDE]: Handle SECTION_EXCLUDE.

	* varasm.c (default_elf_asm_named_section): Don't check if
	HAVE_GAS_SECTION_EXCLUDE is defined.
