Add V=1 to the make command line will show the full commands but by default
we just show the tool-type and the output file. This is generally much easier
on the eye and makes warnings and errors more clearly visible.
Setting the tag type will let libtool work even when it cannot infer
the type of the code being built. One way libtool may fail to infer
the tag type is if one uses a mock compiler (such as for static
analysis).
