Add the alpha MD files for gcc to product ELF for FreeBSD/Alpha.

See freebsd.h and freebsd-elf.h for the silly comment that cgd@netbsd.org
wanted me to add about his claim that uncommented source files that
have been publicly available for ftp for nearly a year; that are
configuration patches to a GPL'ed program; are owned by his previous
employer who refuses to release them. Well... I did as he said. As if
that makes a difference!

At this point we've got cpp, gcc, g++ ported to FreeBSD/Alpha so all
the code that uses __FreeBSD__ is correctly pre-processed. Yay.

I'll commit the bootstrap makefile next to let others play, then on
to libc.

+/* XXX */
+/*
+ * 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.
