Teach BuildDepends test to cover LINK_DEPENDS_NO_SHARED
Build a shared library and an executable linking to it inside the inner
test. Set LINK_DEPENDS_NO_SHARED on the executable. Add a custom
target to compare the output file times. Verify that on the first build
the executable is newer than the library. Then modify a library source
file. Verify that on the second build the library is newer because the
executable did not have a dependency to re-link.
