Subject: configure.ac (HAVE_AS_NO_SHARED): New AC_DEFINE.

gcc/
	* configure.ac (HAVE_AS_NO_SHARED): New AC_DEFINE.  Test for the
	-mno-shared assembler option on mips targets.
	* configure, config.in: Regenerate.
	* config/mips/linux.h (NO_SHARED_SPECS): New macro.
	(DRIVER_SELF_SPECS): Define to NO_SHARED_SPECS if non-empty.
	* config/mips/linux64.h (DRIVER_SELF_SPECS): Include NO_SHARED_SPECS.
