[Xtensa] update include/xtensa-config.h to match gcc

[-- Attachment #1: Type: text/plain, Size: 310 bytes --]

I've committed this patch to update the xtensa-config.h header.  This isn't 
currently needed for binutils or gdb, but the file needs to stay in sync with gcc.

	* xtensa-config.h (XCHAL_HAVE_THREADPTR): New.
	(XCHAL_HAVE_RELEASE_SYNC, XCHAL_HAVE_S32C1I): New.
