tools: tweak tools/libs/libs.mk for being able to support libxenctrl
tools/libs/libs.mk needs to be modified for being able to support building libxenctrl, as the pkg-config file of that library is not following the same conventions as those of the other libraries. So add support for specifying PKG_CONFIG before including libs.mk. In order to make life easier for unstable libraries like libxenctrl set MAJOR and MINOR automatically to the Xen-version and 0 when not specified. This removes the need to bump the versions of unstable libraries when switching to a new Xen version. As all libraries built via libs.mk require a map file generate a dummy one in case there is none existing. This again will help avoiding the need to bump the libarary version in the map file of an unstable library in case it is exporting all symbols. The clean target is missing the removal of _paths.h. Finally drop the foreach loop when setting PKG_CONFIG_LOCAL, as there is always only one element in PKG_CONFIG. Signed-off-by: Juergen Gross <jgross@suse.com> Acked-by: Wei Liu <wl@xen.org>
