[svn-r11471] Purpose:
revision.

Description:
The copyright notice for Makefile(in) were fixed at the beginning of the files.
But they are now generated by automake and autoconf such that Gnu jams its
own copyright block at the beginning.

Solution:
Changed the rule such that the HDF5 copyright notice can be somewhere else
in the file as long as they are together as one paragraph.

Also added recognition of Makefile.am as a possible MAKEFILE type.

Platforms tested:
Tested by hand in heping.
