New crosstap python implementation is total replacement for
crosstap shell script, that has superseding capabilities.
New script support cross compiling of SystemTap scripts
for user-land, by using supplied image rootfs. Whereas old
script could only deal with scripts against kernel. New script
has more complex logic and additional capabilities.
As invocation interface new script support old "legacy"
mode and provides alternative new regular options interface
to access additional functionality.

The crosstap script needed to be updated for recipe specific sysroot
changes including adding support for finding the systemtap binaries.

systemtap_target_arch() should also translate x86-64 (hyphenated) into
x86_64 for the -a param. Failing to do that causes systemtap to see
an architecture mismatch and create a cloned session with a bogusly
synthesized build directory path, and fails to compile the probe.

This script makes it easy to run a systemtap script on a remote target
from a build host.
The script itself contains documentation on basic setup and usage -
see that for details. In a nutshell, if you have a systemtap script
on the build host, this script allows that systemtap script to be
compiled and run on the target host and for the output appear on the
host terminal.
The crosstap script requires to an sdk build of the target (or a build
with 'tools-profile' added to EXTRA_IMAGE_FEATURES) because it needs
to be able to run the native systemtap built by the systemtap recipe,
which in turn needs access to the kernel built for the target in order
to build the kernel modules that implement the systemtap probe
specified by the systemtap script and which ultimately get shipped to
the target and insmod'ed there.
The crosstap script also needs to be able to ssh to the target host in
order insert the modules on the target, so the target system needs to
support incoming ssh connections.
