89fe547f2a Add preliminary support for truss on MIPS. It compiles, but has not 
been extensively tested.  And the ELF64 stuff likely is not quite
right...

# There's a lot of cut-n-paste code here that could easily be
# refactored, at least for FreeBSD syscalls.

9a55503ec1 Teach truss about 32-bit FreeBSD and Linux binaries on amd64. Some 
additional work is needed to handle ABI-specific syscall argument parsing,
but this gets the basic tracing working.

5d2d083c92 Make use of ptrace(2) instead of procfs in truss(1), eliminating 
yet another need of an available /proc/ mount.

72aa911a29 When doing the initial open of the proc via procfs, complain if we are 
unable to open the /proc/pid/mem file.  Otherwise doing a truss on
a nonexistant pid makes us return success even though no such process
exists.

a5d31d1631 A first stab at truss support for amd64, basically cogged from i386. 
It seems to work in my limited tests.

1bcb5f5a96 Port truss(1) to 64-bit architectures: 
o  Syscall return values do not fit in int on 64-bit architectures.
   Change the type of retval in <arch>_syscall_exit() to long and
   change the prototype of said function to return a long as well.
o  Change the prototype of print_syscall_ret() to take a long for
   the return address and change the format string accordingly.
o  Replace the code sequence
	tmp = malloc(X);
	sprintf(tmp, format, ...);
   with X by definition too small on 64-bit platforms by
        asprintf(&tmp, format, ...);

With these changes the output makes sense again, although it does
mess up the tabulation on ia64. Go widescreen...

Not tested on: alpha, sparc64.
