Subject: stap autoconf test for kernel stack trace support

	* buildrun.cxx (compile_pass): Add autoconf line for stack trace
	test, which defines STAPCONF_KERNEL_STACKTRACE.
	* runtime/autoconf-save-stack-trace.c: New file.
	* runtime/stack.c : Use STAPCONF_KERNEL_STACKTRACE instead of
	tests for kernel configuration and versions.
	* runtime/stack-i386.c : ditto
	* runtime/stack-x86_64.c : ditto
