misleading note in libtool header

[Ralf Wildenhues]

For example, CVS GraphicsMagick libtoolized with CVS HEAD Libtool
creates a libtool script with this in the first few lines:

# libtool - Provide generalized library-building support services.
# Generated automatically by config.status (GNU GraphicsMagick) 1.2.020051210

This is misleading and wrong.  We hardwire the `GNU' in libtool.m4's
_LT_CONFIG:
| # Generated automatically by $as_me (GNU $PACKAGE$TIMESTAMP) $VERSION

Either that should be hard-coded to always show the actual Libtool
version this corresponds to, or the `GNU' should not be there.

Suggestions?

Cheers,
Ralf
