gdb: Add sparc*-*-linux catch syscall support.

2010-02-24  David S. Miller  <davem@davemloft.net>

	* gdb_ptrace.h (PT_SYSCALL): If PTRACE_SYSCALL is available, use it.
	* syscalls/sparc-linux.xml: New.
	* syscalls/sparc64-linux.xml: New.
	* Makefile.in (XML_SYSCALL_FILES): Add new syscall XML files.
	* sparc-linux-tdep.c (XML_SYSCALL_FILENAME_SPARC32): Define.
	(sparc32_linux_get_syscall_number): New function.
	(sparc32_linux_init_abi): Set syscall XML file name and hook up
	syscall number fetcher.
	* sparc64-linux-tdep.c (XML_SYSCALL_FILENAME_SPARC64): Define.
	(sparc64_linux_get_syscall_number): New function.
	(sparc64_linux_init_abi): Set syscall XML file name and hook up
	syscall number fetcher.
