RFR: JDK-8210944 Stop replacing -MD with -MT in libwindowsaccessbridge

[Magnus Ihse Bursie]

Currently, we are filtering out -MD and replacing it with -MT when 
building libwindowsaccessbridge. This has just been a way to replicate 
the behavior of old build system, and there's no point in doing so.

In fact, it is recommended *not* to mix -MT and -MD in dlls and 
executable, as that might lead to problems (as seen in e.g. JDK-8207139).
