[Xen-devel] [PATCH 09/11] build system: Introduce nosharedlibs variable.

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

Introduce a new build variable "nosharedlibs".

In tools/libxc use it instead of $(stubdom).
In tools/xenstore honour it, and build static clients.

If shared libs are disabled, do not try to install or symlink them.

Set nosharedlibs when building for MiniOS or NetBSDRump.
