Subject: ntfs-3g: Fix cm-13 compatibility

CM-13 tree completely changes the names of the binaries that are created
for ntfs-3g.  If we are using a CM-13 tree (CM SDK 4) make sure the
dependencies and relinking are adjusted accordingly.

Also, adapt partition code so it can make use of whichever set of
binaries are present.
