The new feature introduced in 23401:a44b12ee2fd3 was broken; it in
general always fails, at least if there are no hotplug scripts.
If there are no hooks, call_hooks ends up running this:
[ -x ".....*.hook" ] && . "..... *.hook"
This does not directly trigger set -e and sigerr. However, it is the
last command exected in call_hooks. So the return status of
call_hooks is an error, and thus a sigerr happens when call_hooks
returns.
The bug affects xl and xm. However xl does not detect failure of the
hotplug script.
Change the script to use if...then rather than &&, as the latter has
very confusing and undesirable semantics.

- Have the buid system generate a file which exports the install paths
for the hotplug scripts and stubdom / stubdom-dm
- Move file generation code from tools/python/Makefile into a gmake
macro
in Config.mk to avoid maintenance of three duplicates each with its
own
tweaks and bugs
- Export gmake variables into ioemu as shell variables
for upcoming ioemu patches
- Do above as a gmake macro to avoid maintenance of several duplicates
- Adjust hotplug scripts to find the right xen binaries from the
install directory
- Adjust stubdom-dm to use the install directories
