Don't check for -xbrace_comment with Solaris/x86 as

With Solaris/x86 as, GCC uses the -xbrace_comment option if supported.
Since it is present in the Solaris 11.4 FCS assembler and 11.4 is the
only supported Solaris version, this check is no longer necessary.

Bootstrapped without regressions on i386-pc-solaris2.11.

	gcc:
	* configure.ac (gcc_cv_as_ix86_xbrace_comment): Remove.
	* configure: Regenerate.
	* config.in: Regenerate.
	* config/i386/sol2.h (ASM_XBRACE_COMMENT_SPEC): Adapt guard.
