 Add short library names support to Windows linker

 Make Linker.hs try asking gcc for lib%s.dll as well, also changed tryGcc
 to pass -L to all components by using -B instead. These two fix
 shortnames linking on windows.

 re-enabled tests: ghcilink003, ghcilink006 and T3333
 Added two tests: load_short_name and enabled T1407 on windows.
