Fixes to GetPrerequisites for cygwin 

Fix IF(WIN32) guards check for cygwin. Fix checking if the depenency is in a system location to use cygwin style paths on cygwin. Also change GetPrerequisites to switch gp_tool to tools that are very unlikely to be found, ie. dumpbin on Apple and otool on Windows/Unix.
