Xen devel - Mar 2007 - [PATCH] - use -p with INSTALL to reduce rebuilds

I do a fair number of builds, and also build other, user applications
based upon libraries and .h files.  The attached patch adds the -p
option to install to retain the source file times. This prevents
unnecessary rebuilds.  Additionally, a few errant INSTALL and install
lines are cleaned up.

An optional approach would be to modify the base INSTALL definition,
but I chose to use the more specific approach in the patch.  FUD is
a powerful force.

If we have build rules depending on the install target, rather than source,
that should probably be fixed in preference.
