With this patch applied on xen tree (see commit 54f2891), the libraries will always be
copied in /usr/local/lib even if --prefix=/usr is specified to the configure.

It's a bit annoying as I used this options daily to build Xen and we have test suite relying
on this option.

Here my config/Paths.mk generated:

# Xen system configuration
# ========================
#
# Xen uses a set of variables for system configuration and at build time,
# because of this these variables are defined on one master input source file
# and is generated after running ./configure. The master source is located
# on the xen source tree at under config/Paths.mk.in and it is used to
# generate shell or header files by the build system upon demand through the
# use of the helper makefile helper buildmakevars2file().
#
# For more documentation you can refer to the wiki:
