ia64: implement sotruss support

Tested with:
	$ cat test.c
	main(){close(0x1024, 2, 3);}
	$ gcc test.c
	$ sotruss -e ./a.out
		a.out -> libc.so.6.1    : __libc_start_main(0x4000000000000950, 0x1, 0x60000fffffb56bc8)
		a.out -> libc.so.6.1    : close(0x1024, 0x2, 0x3)
		a.out -> libc.so.6.1    : close - 0xffffffffffffffff

ia64: ioperm: clean up long dead code

This file has a few #if 0 code paths which cause a build time warning:
ports/sysdeps/unix/sysv/linux/ia64/ioperm.c:66:7: warning:
	variable 'prot' set but not used [-Wunused-but-set-variable]

Rather than add more #if 0 around that variable, just delete the code
altogether.  Not like it's going to ever be implemented.
