* Makefile.am (hosted_source): Add libmath and testsuite.
	(SUBDIRS): Remove them.
	* acinclude.m4: (GLIBCXX_ENABLED_HOSTED): Default to freestanding
	on arm*-*-symbianelf*.
	* crossconfig.m4: Add arm*-*-symbianelf* support.
	* include/c_std/std/std_cstdlib.h (stdlib.h): Do not include it
	when freestanding.  Do not bring names into std:: namespace with
	"using" when freestanding.  Declare required functions and macros
	when freestanding.
