sourceware now provides a more central location where specific versions
of some tools can be installed. Git and Python have now been installed
there, so update the scripts accordingly.
Unfortunately, both git and Python are too old on sourceware.org, so
a local install has been made as a workaround, and this patch updates
the PATH to use them from the two scripts that our hooks define.
Note that this is not completely exhaustive, since other operations
get performed by git outside of hooks, and those can still cause
trouble during the testsuite run. But, for now, things seem to be
relatively in control, as the number of failures associated to that
are fairly small, and can be controlled by hand.
These hooks are deployed on two different machines where the location
of the cvs_check program is different, depending on the machine.
Allow either location.
Get rid of the location that references /jouy.a, and use /svn/Dev/hooks
instead.
For M130-007.
The previous location was the one used on kani, but wasn't canonical.
We're now switching over to moorea, where the incorrect path has been
fixed.
