[Xen-devel] [PATCH v2 for-xen-4.5] Fix configure --with-systemd-modules-load=DIR

[Olaf Hering <olaf@xxxxxxxxx>]

Currently --with-systemd=DIR1 --with-systemd-modules-load=DIR2 will set
both XEN_SYSTEMD_DIR and XEN_SYSTEMD_MODULES_LOAD to DIR1. The reason is
that both AC_ARG_WITH() use 'systemd' as the name for the internal
variable. As a result the value of the first option is also use as the
value for the second option. Fix this by using another variable name.

Please rerun autogen.sh after applying this patch.

v2: use hyphens instead of underscores. Appears to work either way.
