prefix/winnt/profile.bashrc: no symlink usr/lib/NAME.dll

While moving usr/lib/NAME.dll into usr/bin/ is necessary, creating the
symlink usr/lib/NAME.dll -> ../bin/NAME.dll is problematic, because the
libtool .exe wrapper may add usr/lib to PATH, causing the native loader
to fail when attempting to load a dll but discovering a cygwin symlink.
Also, need to resolve symlinks while moving from usr/lib into usr/bin.
