Changes for Alpha and EGCS.

*  Commonalities with i386, moved to a FreeBSD wide config file.
*  Major additions to this file were adapted from Hidetoshi Shimokawa
   <simokawa@FreeBSD.ORG>'s Alpha suppliment to the Egcs 1.1.2 port.

- * This file was derived from source obtained from NetBSD/Alpha which
- * is publicly available for ftp. The patch was developed by cgd@netbsd.org
- * during the time he worked at CMU. He claims that CMU own this patch
- * to gcc and that they have not (and will not) release the patch for
- * incorporation in FSF sources. We are supposedly able to use the patch,
- * but we are not allowed to forward it back to FSF for inclusion in
- * their source releases.
- *
- * This all has me (jb@freebsd.org) confused because (a) I see no copyright
- * messages that tell me that use is restricted; and (b) I expected that
- * the patch was originally developed from other files which are subject
- * to GPL.
- *
- * Use of this file is restricted until its CMU ownership is tested.
