rpath-link on Windows

[Ryan Mansfield]

Drive letters are parsed as the rpath-link separator on windows 
preventing cross platform linker users from specifying absolute paths 
that contain drive letters. This change follows the behavior of other 
parts of the linker that assume a single letter followed by a colon is a 
drive specifier.

OK?
