Allow LINK_SEARCH_{START,END}_STATIC props to have default values.

Use the CMAKE_LINK_SEARCH_START_STATIC and CMAKE_LINK_SEARCH_END_STATIC
variables to initialize the LINK_SEARCH_START_STATIC and
LINK_SEARCH_END_STATIC target properties respectively.

+CMAKE_LINK_SEARCH_END_STATIC
+----------------------------
+
+End a link line such that static system libraries are used.
+
+Some linkers support switches such as -Bstatic and -Bdynamic to
+determine whether to use static or shared libraries for -lXXX options.
+CMake uses these options to set the link type for libraries whose full
+paths are not known or (in some cases) are in implicit link
+directories for the platform.  By default CMake adds an option at the
+end of the library list (if necessary) to set the linker search type
+back to its starting type.  This property switches the final linker
+search type to -Bstatic regardless of how it started.
+
+This variable is used to initialize the target property
+LINK_SEARCH_END_STATIC for all targets.
+
+See also CMAKE_LINK_SEARCH_START_STATIC.

+CMAKE_LINK_SEARCH_START_STATIC
+------------------------------
+
+Assume the linker looks for static libraries by default.
+
+Some linkers support switches such as -Bstatic and -Bdynamic to
+determine whether to use static or shared libraries for -lXXX options.
+CMake uses these options to set the link type for libraries whose full
+paths are not known or (in some cases) are in implicit link
+directories for the platform.  By default the linker search type is
+assumed to be -Bdynamic at the beginning of the library list.  This
+property switches the assumption to -Bstatic.  It is intended for use
+when linking an executable statically (e.g.  with the GNU -static
+option).
+
+This variable is used to initialize the target property
+LINK_SEARCH_START_STATIC for all targets.
