Brad King 2e48fe0eec Avoid Intel linker crash in BuildDepends test
The BuildDepends test exercises incremental linking with MSVC and Intel
tools on Windows.  In some cases the Intel compiler creates objects that
cause the MS linker it invokes to crash during incremental linking.  We
avoid the problem for this test by disabling incremental linking.
