Various updates to the INSTALL notes in preparation for 5.0. Changes
are still to come.

branches: 1.9.2; 1.9.4;
Use \*[Lt] and \*[Gt] rather than '<' and '>' directly.

branches: 1.8.12;
Punctuation nit.

Add note on handling the O2 framebuffer, and how to work around the
non-support, by giving instructions for a serial console.

By Daniel Sieger <dsieger@TechFak.Uni-Bielefeld.DE>

branches: 1.6.2; 1.6.6;
s/elf2ecoff/objcopy/

Fix up sgimips install sections to more closely correspond to the current
state of reality: comment out O2 references since 1.6 won't support the
O2, add notes on installing via a net-booted kernel, disk partitioning
(disk must have IRIX volhdr, one-disk split NetBSD/IRIX install has not
been tested and may/may not work). Also expand/add some examples.

XXX: Should add info on the "extra" kernel sets like the INSTALL_INDY,
etc. sets.

Update sgimips portions of release notes to more closely match reality, esp.
after the removal of the kern-GENERIC set from sysinst. While here, fix up
some minor things (wording, bad markup, typoes) in the non-sgimips specific
common portions.
