"make install" overly eager

I'm building an axis2c package for Ubuntu.

After make install DESTDIR=/foo/bar/baz is done, I get all of these:
/foo/bar/baz/usr/share/INSTALL
/foo/bar/baz/usr/share/README
/foo/bar/baz/usr/share/AUTHORS
/foo/bar/baz/usr/share/NEWS
/foo/bar/baz/usr/share/LICENSE
/foo/bar/baz/usr/share/COPYING
/foo/bar/baz/usr/LICENSE
/foo/bar/baz/usr/bin/tools/wsdl2c/README
/foo/bar/baz/usr/INSTALL
/foo/bar/baz/usr/CREDITS
/foo/bar/baz/usr/COPYING
/foo/bar/baz/usr/NEWS
/foo/bar/baz/usr/NOTICE
/foo/bar/baz/usr/AUTHORS

They obvisouly have no place in neither /usr nor /usr/share.

Looking at the Makefile.am's, however, it looks deliberate?
One of them has this:
datadir=
datadir=$(prefix)
data_DATA= samples/server/axis2.xml README \
INSTALL CREDITS COPYING NEWS NOTICE AUTHORS

Also, adding subdirectories in /usr/bin is bad manners
